Ask the Experts: Ensuring the Validity of Cannabis Lab Testing

By Cannabis Industry Journal Staff
No Comments

Cannabis testing laboratories are one of the major players in the industry for protecting public health. Ensuring that laboratory test results are reliable and valid requires a multipronged approach involving method validation, proficiency testing and performing frequent reviews of equipment and processes.

Cannabis testing laboratories often use a variety of different methods to conduct proficiency testing. Laboratories can either participate in programs run by ISO/IEC 17043-accedited proficiency testing providers or through intralaboratory comparison. Comparing different instruments, methods, technologies against pre-defined criteria is a must when validating methods for a specific type of test and ensuring the competence of the laboratory.

Beyond proficiency testing, there are a number of other stopgaps at a laboratory’s disposal for ensuring valid results, like using accredited certified reference materials, performing checks on measuring equipment frequently, reviewing reported results and retesting retained items. All of that and more is outlined in the ISO/IEC 17025:2017 standard, section 7.7.

What good is a test result if you cannot attest to its validity?

There’s a lot that goes into making sure laboratories provide valid results, much of which is detailed in the accreditation process. For more information, we sit down with Keith Klemm, senior accreditation manager for ANSI National Accreditation Board to learn about laboratory accreditation, method validation and other certifications and credentialing available in the cannabis industry.

Q: Why is method validation important for cannabis test methods? 

Keith Klemm: Because cannabis production, testing, and sales is regulated by each individual state, there are very few standard methods for testing cannabis and cannabis-derived products. Non-standard methods or methods developed by the laboratory must be validated to ensure the methods are fit for their intended purpose. What good is a test result if you cannot attest to its validity? There would be no confidence that the results are accurate. Additionally, while organizations such as ISO, AOAC and ASTM are developing standard methods for use in the laboratory, the wide range of products and matrices being tested require modifications to standard methods. Standard methods used outside their intended scope must also be validated, again to ensure the method remains fit for the intended purpose.

Q: We’re pretty familiar with laboratory accreditation. What other accreditations are available in the cannabis industry?

Klemm: Accreditation programs are available for product certification and personnel credentialing, in addition to laboratory accreditation. ANAB’s product certification program was launched in 2020 and is based on the requirements of ISO/IEC 17065. The program combines the requirements of this standard with specific scheme requirements to attest to the competency of certification bodies who then certify products within the scheme. Two schemes are in development specific to the cannabis industry: Cannabis Safety and Quality (CSQ) and PurityIQ. For personnel credentialing, a new Cannabis Certificate Accreditation Program (C-CAP) was developed and is based on ASTM D8403, Standard Practice for Certificate Programs within the Cannabis and Hemp Industries. It also includes any additional state Responsible Vendor Training requirements.

Q: What are the steps to becoming an accredited cannabis testing laboratory, product certification body, or C-CAP organization?

Klemm: The process begins with a request for quote. The organization prepares for the initial assessment by implementing the requirements of the applicable standards, regulatory requirements, and scheme requirements. ANAB believes in a partnership approach to accreditation with a focus on customer needs while ensuring accreditation requirements are met. Once the organization is ready, an initial document review is performed. The accreditation assessment is then performed on-site by technically skilled and knowledgeable assessors. If any nonconformities are encountered, the organization provides a response with cause and corrective actions. Once all nonconformities are resolved and technical review is completed, a scope of accreditation and certificate are provided to the organization. The technical review may vary depending on the accreditation that is being sought, but the general process of accreditation is the same. After accreditation is achieved, the organization moves into a cycle of surveillance and reassessment as defined by the accreditation program and any scheme requirements.

SC Labs Develops Comprehensive Hemp Testing Panel

By Cannabis Industry Journal Staff
No Comments

SC Labs, a cannabis testing company with roots in Santa Cruz, California, announced this week that they have developed a comprehensive hemp testing panel that covers a number of contaminants on a national regulatory level. In the press release, the company says they aim to fill the void of national hemp testing requirements.

The hemp testing panel they have developed purportedly meets testing standards in states that require contaminant levels below a certain action limit. The SC Labs hemp testing panel could theoretically be used for regulatory compliance testing across the country, reaching action limits and analyte levels that meet the strictest state requirements.

The panel tests for pesticides, heavy metals, microbiology, mycotoxins, residual solvents and water activity.

The panel is one sign of progress on the long road to nationally harmonized testing standards. “As an industry, we’ve been advocating for national, standardized, and transparent testing regulations for years now,” says Jeff Gray, CEO of SC Labs. “The government has been slow to respond so we decided it was time to act. As an industry, we’ve been advocating for national, standardized, and transparent testing regulations for years now. The government has been slow to respond so we decided it was time to act.”

SC Labs is headquartered in Santa Cruz, but has licenses in California, Oregon, Texas and Colorado (pending). Their California and Oregon locations are both ISO 17025-accredited and conducting THC-containing cannabis testing, as well as hemp testing.

Kelab Analitica Becomes First Accredited Cannabis Lab in Colombia

Established in 2019, Kelab Analitica is the first laboratory in Colombia to specialize in cannabis and pharmaceutical testing. In March of 2020, the lab began operating and serving the cannabis market in the South American country.

Then in December of 2020, Kelab Analitica obtained ISO/IEC 17025:2017 through Perry Johnson Laboratory Accreditation, making it the very first cannabis testing lab in Colombia to attain accreditation. The lab was also certified shortly after in Good Laboratory Practices by Colombian health authorities for analysis of pharmaceutical products.

The lab has found that ISO 17025 accreditation has helped with their marketing strategy. “As the industry grows, more producers are beginning to understand the importance of working with an accredited laboratory for quality and consistency of results and to comply with international requirements,” says a team member at Kelab Analitica.

In the future, they plan to expand their reach locally in Colombia and look for opportunities to expand in Latin America. They are also engaged in research in chromatography and instrumentation to develop new cannabis testing methods.

ISO/IEC 17025 Accreditation Falls Short for Cannabis Testing Laboratories

What is the role of the Quality Control (QC) Laboratory?

The Quality Control (QC) laboratory serves as one of the most critical functions in consumer product manufacturing. The QC laboratory has the final say on product release based on adherence to established product specifications. Specifications establish a set of criteria to which a product should conform to be considered acceptable for its intended use. Specifications are proposed, justified and approved as part of an overall strategy to ensure the quality, safety, and consistency of consumer products. Subsequently, the quality of consumer products is determined by design, development, Good Manufacturing Practice (GMP) controls, product and process validations, and the specifications applied throughout product development and manufacturing. These specifications are specifically the validated test methods and procedures and the established acceptance criteria for product release and throughout shelf life/stability studies.

The Code of Federal Regulations, 21 CFR Part 211, Good Manufacturing Practice for Finished Pharmaceuticals, provides the minimum requirements for the manufacture of safe products that are consumed by humans or animals. More specifically, 21 CFR Part 211: Subpart I-Laboratory Controls, outlines the requirements and expectations for the quality control laboratory and drug product testing. Additionally, 21 CFR Part 117, Current Good Manufacturing Practice, Hazard Analysis, and Risk-Based Preventative Controls for Human Food: Subpart B-Processes and Controls states that appropriate QC operations must be implemented to ensure food products are safe for consumption and food packing materials and components are safe and fit for purpose. Both food and drug products must be tested against established specifications to verify quality and safety, and laboratory operations must have the appropriate processes and procedures to support and defend testing results.

ISO/IEC 17025, General Requirements for the Competence of Testing and Calibration Laboratories is used to develop and implement laboratory management systems. Originally known as ISO/IEC Guide 25, first released in 1978, ISO/IEC 17025 was created with the belief that “third party certification systems [for laboratories] should, to the extent possible, be based on internationally agreed standards and procedures”7. National accreditation bodies are responsible for accrediting laboratories to ISO/IEC 17025. Accreditation bodies are responsible for assessing the quality system and technical aspects of a laboratory’s Quality Management System (QMS) to determine compliance to the requirements of ISO/IEC 17025. ISO/IEC 17025 accreditation is pursued by many laboratories as a way to set them apart from competitors. In some cannabis markets accreditation to the standard is mandatory.

The approach to ISO/IEC 17025 accreditation is typically summarizing the standard requirements through the use of a checklist. Documentation is requested and reviewed to determine if what is provided satisfies the item listed on the checklist, which correlate directly to the requirements of the standard. ISO/IEC 17025 covers the requirements for both testing and calibration laboratories. Due to the wide range of testing laboratories, the standard cannot and should not be overly specific on how a laboratory would meet defined requirements. The objective of any laboratory seeking accreditation is to demonstrate they have an established QMS. Equally as critical, for product testing laboratories in particular, is the objective to establish GxP, “good practices”, to ensure test methods and laboratory operations verify product safety and quality. ISO/IEC 17025 provides the baseline, but compliance to Good Laboratory Practice (GLP), Good Manufacturing Practice (GMP) and even Good Safety Practices (GSP) are essential for cannabis testing laboratories to be successful and demonstrate testing data is reliable and accurate.

Where ISO/IEC 17025 accreditation falls short

Adherence to ISO/IEC 17025, and subsequently receiving accreditation, is an excellent way to ensure laboratories have put forth the effort to establish a QMS. However, for product testing laboratories specifically there are a number of “gaps” within the standard and the accreditation process. Below are my “Top Five” that I believe have the greatest impact on a cannabis testing laboratory’s ability to maintain compliance and consistency, verify data integrity and robust testing methods, and ensure the safety of laboratory personnel.

Standard Operating Procedures (SOPs)

The understanding of what qualifies as a Standard Operating Procedure (SOP) is often misunderstood by cannabis operators. An SOP is a stand-alone set of step-by-step instructions which allow workers to consistently carry out routine operations, and documented training on SOPs confirms an employee’s comprehension of their job tasks. Although not required per the current version of the standard, many laboratories develop a Quality Manual (QM). A QM defines an organization’s Quality Policy, Quality Objectives, QMS, and the procedures which support the QMS. It is not an uncommon practice for cannabis laboratories to use the QM as the repository for their “procedures”. The intent of a QM is to be a high-level operations policy document. The QM is NOT a step-by-step procedure, or at least it shouldn’t be.

Test Method Transfer (TMT)

Some cannabis laboratories develop their own test methods, but a common practice in many cannabis laboratories is to purchase equipment from vendors that provide “validated” test methods. Laboratories purchase equipment, install equipment with pre-loaded methods and jump in to testing products. There is no formal verification (what is known as a Test Method Transfer (TMT)) by the laboratory to demonstrate the method validated by the vendor on the vendor’s equipment, with the vendor’s technicians, using the vendor’s standards and reagents, performs the same and generates “valid” results when the method is run on their own equipment, with their own technician(s), and using their own standards and reagents. When discrepancies or variances in results are identified (most likely the result of an inadequate TMT), changes to test methods may be made with no justification or data to support the change, and the subsequent method becomes the “validated” method used for final release testing. The standard requires the laboratory to utilize “validated” methods. Most laboratories can easily provide documentation to meet that requirement. However, there is no verification that the process of either validating in house methods or transferring methods from a vendor were developed using any standard guidance on test method validation to confirm the methods are accurate, precise, robust and repeatable. Subsequently, there is no requirement to define, document, and justify changes to test methods. These requirements are mentioned in ISO/IEC 17025, Step 7.2.2, Validation of Methods, but they are written as “Notes” and not as actual necessities for accreditation acceptance.

Change Control

The standard speaks to identifying “changes” in documents and authorizing changes made to software but the standard, and subsequently the accreditation criteria, is loose on the requirement of a Change Control process and procedure as part of the QMS. The laboratory is not offered any clear instruction of how to manage change control, including specific requirements for making changes to procedures and/or test methods, documented justification of those changes, and the identification of individuals authorized to approve those changes.

Out of Specification (OOS) results

The documentation and management of Out of Specification (OOS) testing results is perhaps one of the most critical liabilities witnessed for cannabis testing laboratories. The standard requires a procedure for “Nonconforming Work”. There is no mention of requiring a root cause investigation, no requirement to document actions, and most importantly there is no requirement to document a retesting plan, including justification for retesting. “Testing into compliance”, as this practice is commonly referred to, was ruled unacceptable by the FDA in the highly publicized 1993 court case United States vs. Barr Laboratories.

Laboratory Safety

FDAlogoSafe laboratory practices are not addressed at all in ISO/IEC 17025. A “Culture of Safety” (as defined by the Occupational Safety and Health Administration (OSHA)) is lacking in most cannabis laboratories. Policies and procedures should be established to define required Personal Protective Equipment (PPE), the safe handling of hazardous materials and spills, and a posted evacuation plan in the event of an emergency. Gas chromatography (GC) is a common test method utilized in an analytical testing laboratory. GC instrumentation requires the use of compressed gas which is commonly supplied in gas cylinders. Proper handling, operation and storage of gas cylinders must be defined. A Preventative Maintenance (PM) schedule should be established for eye wash stations, safety showers and fire extinguishers. Finally, Safety Data Sheets (SDSs) should be printed and maintained as reference for laboratory personnel.

ISO/IEC 17025 accreditation provides an added level of trust, respect and confidence in the eyes of regulators and consumers. However, the current process of accreditation misses the mark on the establishment of GxP, “good practices” into laboratory operations. Based on my experience, there has been some leniency given to cannabis testing laboratories seeking accreditation as they are “new” to standards implementation. In my opinion, this is doing cannabis testing laboratories a disservice and setting them up for failure on future accreditations and potential regulatory inspections. It is essential to provide cannabis testing laboratory owners and operators the proper guidance from the beginning and hold them up to the same rigor and scrutiny as other consumer product testing laboratories. Setting the precedence up front drives uniformity, compliance and standardization into an industry that desperately needs it.

In a press release sent out this week, Trichome Analytical, based in Mount Laurel, New Jersey, announced two new developments for their business: They have achieved ISO 17025:2017 accreditation and they are officially registered with the DEA for hemp compliance testing.

The press release also mentions their collaboration with Shimadzu, who supplies 80% of the lab’s equipment and supports the Trichome’s operations with technical guidance.

For the hemp industry, pre-harvest testing for THC levels is a requirement and labs are required to get registered with the DEA in order to perform that testing.

These announcements are somewhat timely, given the results of the election. Voters in New Jersey approved adult use cannabis legalization just last week.

According to a press release published July 1, ASI Global Standards announced the launch of their newest audit standard: the Cannabis Safety & Quality Scheme (CSQ). The scheme is built around ISO requirements and the Global Food Safety Initiative (GFSI) requirements.

With input from a number of stakeholders in the cannabis space, the CSQ scheme is designed for the cannabis industry and by the cannabis industry. Each standard was developed by industry professionals and stakeholders, like growers, manufacturers and processors, to meet market, consumer and regulatory requirements from seed-to-sale.

The CSQ scheme is built on four standards:

  • Growing and Cultivation of Cannabis Plants
  • Manufacturing and Extraction of Cannabis
  • Manufacturing and Infusion of Cannabis into Food & Beverage Products
  • Manufacturing of Cannabis Dietary Supplements

There is a public comment period in effect now, and those wishing to provide input have until July 31 to do so. If certification bodies or accreditation bodies want to find more information and get involved in the CSQ certification or accreditation process, they are encouraged to reach out via email at info@csqcertification.com.

Deibel Bioscience Rebrands, Achieves ISO 17025 Accreditation

By Cannabis Industry Journal Staff

On June 19, Charles Deibel, president and CEO of Deibel Bioscience, announced two important changes to his cannabis testing laboratory: First, they changed their name from Deibel Laboratories to Deibel Bioscience. Secondly, they achieved ISO/IEC 17025:2017 accreditation.

Deibel Labs is an internationally recognized corporation of 15 testing labs in North America that’s been around for about 50 years, serving the food, beverage and personal care industries. Starting in 2018, Deibel has ventured into the cannabis and hemp markets, and recently rebranded these labs as “Deibel Bioscience.” Currently, Deibel Bioscience operates in California and Illinois, with plans underway to open labs in Florida and Pennsylvania.

Charles Deibel, President & CEO of Deibel Bioscience

Deibel’s brand is very well known in the food testing industry and has recently become a prominent voice and industry advocate in the cannabis testing community. Charles Deibel’s father, Dr. Robert Deibel, was a pioneer of the Hazard Analysis and Critical Control Point (HACCP) system. Charles Deibel has a long career in the laboratory testing space and even worked with the Department of Justice to help shape the legal case against Peanut Corporation of America and testified as an expert witness during the trial.

With respect to their accreditation, Deibel Bioscience of California (Santa Cruz) achieved it through the American Association for Laboratory Accreditation (A2LA). The lab’s scope currently holds seven chemical and microbiological test methods as well as their sampling method, with plans to expand their scope to include four more chemical testing methods in the next month.

“At our level of testing services, any lab should be able to offer accurate testing, at a fair price and a reasonable turn-around time,” says Deibel. “These three qualities are no longer defining features; rather it is our high level of service and exceptional Technical Services acumen that set us apart.”

According to Deibel, their company is drawing on decades of experience in other testing industries to provide a high caliber of technical expertise. “We are a family owned and operated corporation and are not constrained by quarterly investor demands. Our size offers economics of scale that is reflected in our service and pricing.”

ACS Laboratory Get Certified for Cannabis Testing in Florida

By Cannabis Industry Journal Staff
No Comments

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.
