According to a press release published earlier this week, ACS Laboratory announced the Florida Department of Health Office of Medical Marijuana Use (OMMU) has certified ACS to test products for medical dispensaries in the state.
This certification comes after the Florida Department of Health adopted an emergency rule, requiring dispensaries to only use a certified lab for product testing. Dispensaries (or medical marijuana treatment centers as the state calls them) in Florida have until December 24, 2020 to sell products tested before June 24, 2020.
ACS Laboratory was founded in 2008. They are DEA- and AHCA-licensed, ISO 17025-accredited and CLIA-accredited with the largest testing facility in the eastern United States, according to their press release. They are USDA-compliant and certified by Florida to test hemp in the state and are now also certified to test medical cannabis products.
As a certified cannabis testing lab in Florida, ACS has to meet a list of requirements, similar to rules one might find in other legal states. The Florida rules mandate that labs are ISO-accredited and qualified to accurately test for contaminants, moisture content and cannabinoid potency.
Earlier this year, ACS acquired Botanica Testing, Inc., which added about 500 new hemp and CBD clients to their portfolio. ACS Laboratory now has customers in 44 states.
While legalization of recreational cannabis remains in a fluid state in the United States, the medical application of cannabis is gaining popularity. As such, the diversification of pharmaceutical and edible cannabis products will inevitably lead to increased third party testing, in accordance with Food and Drug Administration (FDA) mandates. Laboratories entering into cannabis testing, in addition to knowing the respective state mandates for testing procedures, should be aligned with Federal regulations in the food and pharmaceutical industries.
In 2010, the American Herbal Products Association (AHPA)1 established a cannabis committee with the primary objective of addressing issues related to the practices and safe use of legally-marketed cannabis and cannabis-related products. The committee issued a set of recommendations, outlining best practices for the cultivation, processing, testing and distribution of cannabis and cannabis products. The recommendations for laboratory operations sets some basic principles for those performing analysis of cannabis products. These principles, complementary to existing good laboratory practices and international standards, focus on the personnel, security, sample handling/disposal, data management and test reporting unique to laboratories analyzing cannabis samples.
As local and federal regulations continue to dictate medical and recreational cannabis use, many will venture into the business of laboratory testing to meet the demands of this industry. Thus, it is not surprising that cannabis producers, distributors and dispensaries will need competent testing facilities to provide reliable and accurate results. In addition, our understanding of cannabis from an analytical science perspective will derive from test reports received from these laboratories. Incorrect or falsified results can be costly to their business and can even lead to lawsuits when dealing with consumer products. Examples of fines and/or suspensions related to incorrect/false reporting of results have already gained coverage in news media. This sets up the need for the cannabis industry to establish standardized protocols for laboratory competency.
The international standard, ISO 17025 – ‘General requirements for the competence of testing and calibration laboratories’ – plays an important role in providing standard protocols to distinguish labs with proven quality, reliability and competency. The industry needs to rely not only on the initial accreditation received, but also on the ongoing assessment of the labs to ensure continuous competency.
Receiving accreditation involves an assessment by an International Laboratory Accreditation Cooperation (ILAC) recognized accrediting body, which ensures that laboratories have the competency, resources, personnel and have successfully implemented a sound quality management system that complies with the international standard ISO/IEC 17025:2017. This ISO standard is voluntary, but recognized and adopted globally by many industries for lab services. Cannabis companies can ensure that the test services they receive from accredited laboratories will meet the requirements of the industry, as well as the state and federal regulatory agencies. The International Organization for Standardization (ISO) is an independent, non-governmental organization with over 160 memberships of national standards bodies, and all with a unified focus on developing world-class standards for services, systems, products, testing to ensure quality, safety, efficiency and economic benefits.
ILAC is a non-profit organization made up of accreditation bodies (ABs) from various global economies. The member bodies that are signatories to the ILAC Mutual Recognition Arrangement (ILAC MRA) have been peer evaluated to demonstrate their competence. The ILAC MRA signatories, in turn, assess testing labs against the international standard, ISO/IEC 17025 and award accreditation. Accreditation is the independent evaluation of conformity assessment in accordance with the standard and related government regulations to ensure the lab carry out specific activities (called the ‘Scope’) impartially and competently. Through this process, cannabis industry stakeholders and end users can have confidence in the test results they receive from the labs.
Understanding the principles of accreditation and conformity to ISO standards is the beginning of the ISO 17025 accreditation process. Similar to other areas of testing, accreditation gives cannabis testing labs global recognition such that their practices meet the highest standards in providing continuous consistency, reliability and accuracy.
Many government agencies (state and federal) in the US and around the world are mandating cannabis testing laboratories to seek accreditation to ISO/IEC 17025:2017, in an effort to standardize their practice and provide the industry with needed assurance. Conformance with the standard enables labs to demonstrate their competency in generating reliable results, thereby providing assurance to those who hire their services.
Testing of cannabis can be very demanding and challenging given that state and federal regulations require that the performance and quality of the testing activities must provide consistent, reliable and accurate results. Hence, labs deciding to set up cannabis testing will have to take extra care in setting up a laboratory facility, acquiring all necessary and appropriate testing equipment, hiring qualified and experience staff and developing and implementing test methods to ensure the process, sample throughput, data integrity and generated output are continuously reliable, accurate and meet the need of the clients and requirements of the regulatory bodies. This demands the lab to establish and implement very sound quality assurance program, good laboratory practices and a quality management system (QMS).
Some expected challenges are:
Standardization of test methods and protocols
Since there is no federal guidance in standardization of test methods and protocols for cannabis testing in US, it is challenging for laboratories to research and validate other similar, established methods and gain approval from the local and state authorities.
Facility
Cannabis testing activities must be physically isolated from other testing activities for those labs conducting business in other areas of testing such as environment, food, mining, etc.
Microbiological testing requires additional physical isolation within the testing facility, maintaining sterility of the environment, test area and test equipment.
Equipment
The test equipment such as Chromatographs (GC/LC), Spectrometers (ICP-MS, ICP-OES, UV-Vis), and other essential analytical instruments must meet the specifications required to detect and quantify and statistically justify the test parameters at the stipulated concentration levels. That means the limit of detection and limit of quantitation of each parameter must be well below the regulatory limits and the results are statistically sound.
Calibration, maintenance and operation of analytical equipment must be appropriate to produce results traceable to international standards such as International System of Units and National Institute of Standards and Technology (SI and NIST).
Staff
The qualification and experience of the staff should ensure standard test methods are implemented and verified to meet the specifications.
They should have a sound understanding of the QA/QC protocols and effective implementation of a quality management system which conforms to ISO/IEC 17025:2017 standard.
Staff should be properly trained in all standard operating procedures (SOPs) and receiving schedule re-training as needed. Training should be accurately documented.
QMS
The QMS should not only meet the requirements of ISO 17025, but also be appropriate to the scope of the laboratory activities. Such a system must be planned, implemented, verified and continuously improved to ensure effectiveness.
Finally, stakeholders should seek expert advice in establishing a cannabis testing lab prior to initiating the accreditation. This can be achieved through a cyclic PLAN-DO-CHECK-ACT process. Labs that are properly established can attain the accreditation process in as little as 3-5 months. An initial ‘Gap Analysis’ can be extremely helpful in this matter.

In a press release published on Monday, the American Association for Laboratory Accreditation (A2LA), announced the renewal of accreditation for Global Laboratory Services, Inc. for ISO 17025:2017 in cannabis testing. The laboratory, based in Wilson, North Carolina, becomes first cannabis testing laboratory accredited in that state by adding the industrial hemp testing to their chemical scope of accreditation.
According to Kim Hesse, business development manager at Global Laboratory Services, they plan to expand their services in the hemp market with additional types of hemp testing. “At Global Laboratory Services, we always strive to keep pace with industry needs,” says Hesse. “We saw the need for an accredited laboratory in the hemp industry and therefore added CBD and THC testing to our scope. Our next step is to expand our service offerings to include agrochemical analysis of industrial hemp.”
Adam Gouker, general manager at A2LA, says accreditation plays a vital role in the cannabis industry and its regulatory requirements. “We congratulate Global Laboratory Services on becoming the first cannabis testing laboratory accredited in the state of North Carolina, specifically for industrial hemp,” says Gouker. “A2LA realizes the vital role that accreditation plays in the cannabis industry to support compliance with regulatory requirements, and we are thrilled to see that our service has been adopted in a new state. We look forward to our continued relationship with Global Laboratory Services in the provision of their accreditation needs.”
Both labs are located in Streetsboro, Ohio, becoming A2LA’s first accredited labs in the state. North Coast Testing does cannabis testing for Ohio’s medical cannabis industry, whereas North Coast Analytical does testing for the hemp industry.
Carolyn Friedrich, Ph.D., scientific director at North Coast Testing, says they are excited to help ensure the safety of patients for Ohio’s medical cannabis program. “We are extremely proud of the work of our entire team in rapidly developing and implementing a comprehensive quality management program that can give all participants in the Ohio Medical Marijuana Control Program confidence in the quality and safety of products tested in our laboratory,” says Friedrich.
Nick Szabo, laboratory director at North Coast Analytical, says A2LA went “above and beyond at every step, we greatly appreciate their efforts. Our accreditation by A2LA is a testament to our ability to meet the most rigorous quality management standards in analytical testing of hemp products, and a vote of confidence in our team’s ability to perform at the highest levels.”
Encore Labs is a full-service cannabis testing lab in Pasadena, California, providing all testing needs required by California’s Bureau of Cannabis Control (BCC). The BCC requires that cannabis products being sold in licensed dispensaries be tested for cannabinoid potency, heavy metals, microbial impurities, moisture content and water activity, mycotoxins, residual pesticides, residual solvents and processing chemicals, foreign materials and terpenes. It is Encore Labs’ goal to guarantee the quality and potency of all cannabis products while ensuring regulatory guidelines are met in the state of California.
Encore Labs provides quick turnaround times on a consistent basis. They take pride in offering excellent customer service without diminishing the quality of the work that they do. Their team of laboratory analysts/technicians are passionate about the industry and will never compromise their integrity just to make an extra buck.
Co-Founder, Spencer Wong, mentions their personal connection with clients. “Our customers don’t just see us as their testing laboratory, they see Encore Labs as their laboratory partner,” says Wong. “Besides performing analytical testing, we have worked with many customers to help formulate new products and do root cause analysis to pinpoint inefficiencies in their manufacturing operations and cultivation farms.”
ISO/IEC 17025 Accreditation has been extremely valuable to Encore Labs, especially regarding the new cannabis testing industry. “Our experience with Perry Johnson Laboratory Accreditation, Inc. has been great and has allowed for a very smooth and straightforward initial accreditation process. Their staff has been knowledgeable and responsive every step of the way,” says Wong.
Accreditation establishes that steps are being taken regarding quality and that laboratories are meeting and exceeding the highest testing standards. It also provides further assurance and confidence in data results as well as validated methods, staff training procedures, equipment calibration and successful participation in proficiency testing/interlaboratory comparisons.
Starting out with 1500 square feet of laboratory space, within the last year Encore Labs has doubled its work area. In order to meet the growing demand of the cannabis testing industry, they have added plans to once again double in size by the end of 2019, as well as open a second laboratory by the end of 2020.
According to a press release issued last week, the American Association for Laboratory Accreditation (A2LA) accredited Legend Technical Services to ISO/IEC 17025:2005 for industrial hemp testing. Legend Technical Services, based in St. Paul, Minnesota, is currently the only accredited cannabis testing in the state.
The lab is now accredited for medical cannabis testing as well as all industrial hemp testing for the Minnesota Department of Agriculture. Trace McInturff, Vice President of Accreditation Services, says Legend Technical Services has been a customer of A2LA for ten years now. “As the only hemp testing laboratory recognized by the Minnesota Department of Agriculture, we are proud they have chosen to expand their A2LA accreditation to include hemp testing,” says McInturff. “We are also very proud to add yet another state to the ever-growing list of states that are relying upon A2LA as their accreditation body.”
According to a press release, Stillwater is also the first in the state to go through a dual assessment, a new program put in place Fall of 2018. Both ISO/IEC 17025 accreditation and Americans for Safe Access (ASA) Patient Focused Certification were obtained by the lab. Stillwater achieved the recently updated ISO 17025:2017 accreditation.
“Stillwater Labs is honored to achieve ISO/IEC 17025:2017 accreditation” says Dr. Ron Brost, laboratory director Stillwater. “Quality methods are the cornerstone of our operations, and accreditation through the A2LA has been a valuable developmental process. We used the opportunity to refine, clarify, and tune our systems in order to bring world-class analytics to our clients in Montana. We look forward to continuing to drive advanced technologies coupled with excellent customer service through ISO/IEC 17025 best practices.”
According to a press release published on April 3, Keystone State Testing (doing business as Dakota State Testing) became the first laboratory authorized to test cannabis in North Dakota. The lab also obtained their ISO 17025 accreditation for cannabis testing from the American Association of Laboratory Accreditation (A2LA), which is another first achievement for cannabis testing in the state of North Dakota.
Dr. Kelly Greenland, chief science officer at Keystone State Testing, says the North Dakota Department of Health set a high standard for the cannabis lab testing industry in the state. “Keystone State Testing is once again proud to of this monumental achievement and critical milestone in the company’s history to have met the highest levels of standards set forth by both A2LA and the North Dakota Department of Health,” says Greenland. “Keystone chose A2LA as its Accreditation Body due to their reputation in the industry, their diverse clientele, and the quality of their assessors. A2LA’s assessors have spent decades in their respective fields, which helps to ensure that Keystone is providing the best services possible to their clients, regulators and patients.”
Keystone State Testing’s ISO 17025 accreditation scope covers 11 testing methods at their facility in Fargo, North Dakota. Those methods include: Cannabinoid potency analysis, cannabinoid profile, moisture content, residual solvents, water activity, along with microbiological tests like total yeast and mold count, E. coli, Salmonella, total aerobic microbial count, among others.
AOAC INTERNATIONAL is an independent, third party, not-for-profit association and voluntary consensus standards developing organization. Founded in 1884, AOAC INTERNATIONAL was originally coined the Association of Official Agricultural Chemists. Later on, they changed their name to the Association of Official Analytical Chemists. Now that their members include microbiologists, food scientists as well as chemists, the organization officially changed its name to just AOAC INTERNATIONAL.
Much of AOAC’s work surrounds promoting food safety, food security and public health. Their work generally encompasses setting scientific standards for testing methodology, evaluating and adopting test methods and evaluating laboratory proficiency of test methods. The organization provides a forum for scientists to develop microbiological and chemical standards.
In December of 2018, they appointed Dr. Palmer Orlandi as deputy executive director and chief science officer. Dr. Orlandi has an extensive background at the U.S. Food and Drug Administration (FDA), serving the regulatory agency for more than 20 years. Most recently, he was the CSO and research director in the Office of Food and Veterinary Medicine at the FDA. He earned the rank of Rear Admiral and Assistant Surgeon General in 2017.
Dr. Palmer Orlandi is the new Deputy Executive Director and Chief Science Officer at AOAC.
Where It All Began With Cannabis
As recently as three years ago, AOAC began getting involved in the cannabis laboratory testing community, with a working group dedicated to developing standard method performance requirements for AOAC Official MethodsSM for cannabis testing. We sat down with Dr. Palmer Orlandi and a number of AOAC’s leaders to get an update on their progress working with cannabis testing as well as food security and food fraud.
According to Scott Coates, senior director of the AOAC Research Institute, they were approached three years ago to set up a working group for cannabis testing. “We created standards that we call the standard method performance requirements (SMPR®), which are detailed descriptions of what analytical methods should be able to do,” says Coates. “Using SMPRs, we issued a series of calls for methods and looked for methods that meet our standards. So far, we’ve completed four SMPRs- cannabinoids in plant material, cannabinoids in plant extracts, cannabinoids in chocolate (edibles), and one for pesticides in cannabis plant material.” AOAC doesn’t develop methods themselves, but they perform a comprehensive review of the methods and if they deem them acceptable, then the methods can be adopted and published in the AOAC compendium of methods, the Official Methods of Analysis of AOAC INTERNATIONAL.
Deborah McKenzie, senior director of Standards and Official Methods at AOAC
Deborah McKenzie, senior director of Standards and Official MethodsSM at AOAC, says the initial working group set the stage for really sinking their teeth into cannabis testing. “It started with methods for testing cannabinoids in plant dried material and plant extract,” says McKenzie. “That’s where our previous work has started to mold into the current effort we are launching.” McKenzie says they are looking forward to getting more involved with methods regarding chemical contaminants in cannabis, cannabinoids in various foods and consumables, as well as microbial organisms in cannabis. “We are pretty focused on testing labs having reliable and validated analytical solutions as our broad goal right now.”
Moving Forward, Expanding Their Programs
Coates says the work they’ve done over the past few years was more of a singular project, developed strictly for creating standards and to review methods. Now they are currently developing their Cannabis Analytical Science Program (CASP), which is expected to be an ongoing program. “We are looking to fully support the cannabis analytical community as best we can, which will potentially include working on reference materials, proficiency testing, education, training and ISO 17025 accreditation, all particularly as it applies to lab testing in the cannabis industry,” says Coates. “So, this CASP work is a much bigger and broader effort to cover more and to provide more support for labs doing the analysis of cannabis and its constituents, as well as hemp.”
According to Dr. Orlandi, they want this program to have a broad reach in the cannabis testing community. “As Scott pointed out, it’s not just strictly developing standards and methods,” says Dr. Orlandi. “It is going to be as all-encompassing as possible and will lead to training programs, a proficiency testing program and other areas.” Arlene Fox, senior director of AOAC’s Laboratory Proficiency Testing Program, says they are actively engaging in proficiency testing. “We are in the process of evaluating what is out there, what is possible and what’s needed as far as expanding proficiency testing for cannabis labs,” says Fox.
Regulatory Challenges & Obstacles
The obvious roadblock to much of AOAC’s work is that cannabis is still considered a controlled substance. “That creates some challenges for the work that we do in certain areas,” says Dr. Orlandi. “That is why this isn’t just a one-year project. We will work with these challenges and our stakeholders to address them.” AOAC had to put some limits on participation- for example, they had to decide that they cannot look for contributions or collaborations with producers and distributors, so long as cannabis is still a Schedule I controlled substance in the US.
Arlene Fox, senior director of AOAC’s Laboratory Proficiency Testing Program
Muddying the waters even further, the recent signing of the Farm Bill puts a clear distinction between most types of cannabis and industrial hemp. David Schmidt, executive director of AOAC realizes they need to be realistic with their stakeholders and in the eye of federal law.
While scientifically speaking, it’s pretty much the same plant just with slightly different chemical constituents, AOAC INTERNATIONAL has to draw a line in the sand somewhere. “As Palmer suggests, because of the Farm Bill being implemented and hemp being defined now as a legal substance from a controlled substance standpoint, industrial hemp has been given this exclusion,” says Schmidt. “So, we are trying to be realistic now, working with our stakeholders that work with hemp, trying to understand the reality of the federal law. We want to make clear that we can meet stakeholder needs and we want to distinguish hemp from cannabis to remain confident in the legality of it.” Schmidt says this is one of a number of topics they plan on addressing in detail at their upcoming 9thannual 2019 Midyear Meeting, held March 11-14 in Gaithersburg, Maryland.
Uniformity in Methodology: The Future of Cannabis Testing
Dr. Orlandi says his experience at the FDA has prepared him well for the work being done at AOAC. “The role that I served at the FDA prior to joining my colleagues here at AOAC was very similar: And that is to bring together stakeholders to accomplish or to solve a common problem.” Some of their stakeholders in the CASP program include BC Testing, Inc., the Association of Food and Drug Officials (AFDO), Bia Diagnostics, Bio-Rad, Industrial Laboratories, Materia Medica Labs, PerkinElmer, R-Biopharm AG, Supra R & D, TEQ Analytical Laboratories, Titan Analytical and Trilogy Analytical, among others.
David Schmidt, executive director of AOAC
“The underlying reason behind this effort is to create some level of harmonization for standards and methods,” says Dr. Orlandi. “They can be used in the near future to stay ahead of the curve for when regulatory agencies become involved. The idea is that these standards for analytical methods will already be established and as uniform as possible.”
When comparing cannabis to other industries in the US, Scott Coates mentions that most standards are signed off by the federal government. “When we started looking at pesticides in cannabis, it became really clear that we have a number of states doing things differently with different limits of quantification,” says Coates. “Each state, generally speaking, is setting their own standards. As Palmer was saying, one thing we are trying to do with this CASP program eventually will be to have some harmonization, instead of 30 different states having 30 different standards and methods.” So, on a much broader level, their goal for the CASP program is to develop a common set of standard methods, including hemp testing and even the Canadian market. “Hopefully this will be an international collaboration for standards for the methodology,” says Coates. They want to create a common set of standards, setting limits of quantification that will be accepted internationally, that will be accurate and repeatable and for the entire cannabis industry, not just state by state.
Food Authenticity & Fraud
One of the other activities that AOAC just launched recently is the food authenticity and fraud program. As the name implies, the goal is to start developing standards and methods and materials to look at economically adulterated foods, says Dr. Orlandi. That includes non-targeted analyses looking at matrices of food products that may be adulterated with an unknown target, as well as targeted analytes, identifying common adulterants in a variety of food products. “One example in the food industry is fraudulent olive oil,” says Dr. Orlandi. “Honey is another commodity that has experienced adulteration.” He says that in most cases these are economically motivated instances of fraud.

As state cannabis regulatory frameworks across the country continue to evolve, accreditation is becoming increasingly important. Because it provides consistent, turnkey standards and third-party verification, accreditation is quickly emerging as an important tool for regulators. For cannabis testing laboratories, this trend has been especially pronounced with the increasing number of states that require accreditation to ISO/IEC 17025.
As of 2017 there were nearly 68,000 laboratories accredited to ISO/IEC 17025, making it the single most important benchmark for testing laboratories around the world. ISO/IEC 17025:2005 specifies the general requirements for the competence to carry out tests including sampling. It covers testing performed using standard methods, non-standard methods and laboratory-developed methods. It is applicable to all organizations performing tests including cannabis labs. The standard is applicable to all labs regardless of the number of personnel or the extent of the scope of testing activities. Developed to promote confidence in the operation of laboratories, the standard is now being used as a key prerequisite to operate as a cannabis lab in many states.
There are currently 26 states in the United States (also Canada) that require medical or adult-use cannabis to be tested as of February 2019. Of those states, 18 require cannabis testing laboratories to be accredited – with the vast majority requiring ISO/IEC 17025 accreditation. States that require testing laboratories to attain ISO/IEC 17025 accreditation represent some of the largest and most sophisticated cannabis regulatory structures in the country, including California, Colorado, Maryland, Massachusetts, Michigan, Nevada and Ohio. As a consequence, many cannabis testing laboratories are taking note of recent changes to ISO/IEC 17025 standards.
ISO/IEC 17025 was first issued in 1999 by the International Organization for Standardization. The standard was updated in 2005, and again in 2017. The most recent update keeps many of the legacy standards from 2005, but adds several components – specifically requirements for impartiality, risk assessment and assessing measurement uncertainty. The remainder of this article takes a deeper dive into these three areas of ISO/IEC 17025, and what that means for cannabis testing laboratories.Objectivity is the absence or resolution of conflicts of interest to prevent adverse influence on laboratory activities.
Impartiality
ISO/IEC 17025:2005 touched on an impartiality requirement, but only briefly. The previous standard required laboratories that belonged to organizations performing activities other than testing and/or calibration to identify potential conflicts of interest for personnel involved with testing or calibration. It further required that laboratories had policies and procedures to avoid impartiality, though that requirement was quite vague.
ISO/IEC17025:2017 emphasizes the importance of impartiality and establishes strict requirements. Under the new standard, labs are responsible for conducting laboratory activities impartially and must structure and manage all laboratory activities to prevent commercial, financial or other operational pressures from undermining impartiality. The definitions section of the standard defines impartiality as the “presence of objectivity.” Objectivity is the absence or resolution of conflicts of interest to prevent adverse influence on laboratory activities. For further elaboration, the standard provides similar terms that also convey the meaning of impartiality: lack of prejudice, neutrality, balance, fairness, open-mindedness, even-handedness, detachment, freedom from conflicts of interest and freedom from bias.
To comply with the new standard, all personnel that could influence laboratory activities must act impartially. ISO/IEC 17025:2017 also requires that laboratory management demonstrate a commitment to impartiality. However, the standard is silent on how labs must demonstrate such commitment. As a starting point, some cannabis laboratories have incorporated statements emphasizing impartiality into their employee handbooks and requiring management and employee training on identifying and avoiding conflicts of interest.
Risk Assessment
Both the 2005 and 2017 versions contain management system requirements. A major update to this is the requirement in ISO/IEC 17025:2017 that laboratory management systems incorporate actions to address risks and opportunities. The new risk-based thinking in the 2017 version reduces prescriptive requirements and incorporates performance-based requirements.
Under ISO/IEC 17025:2017, laboratories must consider risks and opportunities associated with conducting laboratory activities. This analysis includes measures that ensure that:
The lab’s management system is successful;
The lab has policies to increase opportunities to achieve its goals and purpose;
The lab has taken steps to prevent or reduce undesired consequences and potential failures; and
The lab is achieving overall improvement.
Labs must be able to demonstrate how they prevent or mitigate any risks to impartiality that they identify.To comply with ISO/IEC 17025:2017, labs must plan and implement actions to address identified risks and opportunities into management systems. They must also measure the effectiveness of such actions. Importantly, the standard requires that the extent of risk assessments must be proportional to the impact a given risk may have on the validity of the laboratory’s test results.
ISO/IEC 17025:2017 does not require that labs document a formal risk management process, though labs have discretion to develop more extensive methods and processes if desired. To meet the requirements of the standard, actions to address risks can include sharing the risk, retaining the risk by informed decision, eliminating the risk source, pinpointing and avoiding threats, taking risks in order to pursue an opportunity, and changing the likelihood or consequence of the risk.
ISO/IEC 17025:2017 references “risks” generally throughout most of the standard. However, it specifically addresses risks to a laboratory’s impartiality in section 4.1. Note, the new standard requires that labs must not only conduct activities impartially, but also actively identify risks to their impartiality. This requirement is on-going, not annually or bi-annually. Risks to impartiality include risks arising from laboratory activities, from laboratory relationships, or from relationships of laboratory personnel. Relationships based on ownership, governance, shared resources, contracts, finances, marketing, management, personnel and payment of a sales commission or other inducements to perform under pressure can threaten a laboratory’s impartiality. Labs must be able to demonstrate how they prevent or mitigate any risks to impartiality that they identify.
Assessing Measurement Uncertainty With Decision Rules
ISO/IEC 17025:2005 required (only where necessary and relevant) test result reports to include a statement of compliance/non-compliance with specifications and to identify which clauses of the specification were met or not met. Such statements were required to take into account measurement uncertainty and if measurement results and uncertainties were omitted from the statement, the lab was required to record and maintain the results for future reference.
ISO/IEC 17025:2017 requires similar statements of conformity with an added “decision rule” element. When statements of conformity to a specification or standard are provided, labs must record the decision rule it uses and consider the level of risk the decision rule will have on recording false positive or negative test results. Like the 2005 version, labs must include statements of conformity in test result reports (only if necessary and relevant- see 5.10.3.1 (b)). Now, test result reports on statements of conformity must include the decision rule that was employed.
Moving Forward
Because many states require ISO/IEC 17025 accreditation for licensing, cannabis testing labs across the country would be well advised to closely monitor the implications of changes in ISO/IEC 17025:2017 related to impartiality, risk assessment and measurement uncertainty. If you run a cannabis testing lab, the best way to ensure compliance is education, and the best place to learn more about the new requirements is from a globally recognized accreditation body, especially if it is a signatory to the International Laboratory Accreditation Cooperation (ILAC) for testing laboratories, calibration laboratories and inspection agencies.

This certification comes after the Florida Department of Health adopted an emergency rule, requiring dispensaries to only use a certified lab for product testing. Dispensaries (or medical marijuana treatment centers as the state calls them) in Florida have until December 24, 2020 to sell products tested before June 24, 2020.
