According to a press release published earlier this month, the Bio-Rad iQ-Check Aspergilllus Real-Time PCR Detection Kit has received AOAC International approval. The test covers detection for four different Aspergillus species: A. flavus, A. fumigatus, A. niger, and A. terreus.
The detection kit covers those Aspergillus species for testing in cannabis flower and cannabis concentrates, produced with our without solvents. The PCR detection kit was validated through the AOAC Research Institute’s Performance Tested Method Program. They conducted a study that resulted in “no significant difference” between the PCR detection kit and the reference method.
The kit was evaluated on “robustness, product consistency, stability, inclusivity and exclusivity, and matrix studies,” the press release says. Bio-Rad also received approval and validation on the iQ-Check Free DNA Removal Solution, part of the workflow for testing cannabis flower.
The test kit uses gene amplification and real-time PCR detection. Following enrichment and DNA extraction, the test runs their PCR technology, then runs the CFX Manager IDE software to automatically generate and analyze results.
Bio’Rad has also recently received AOAC approval for other microbial testing methods in cannabis, including their iQ-Check Salmonella II, iQ-Check STEC VirX, and iQ-Check STEC SerO II PCR Detection Kits.
Communication is key for efficient interaction between cultivation and business functions at any cannabis operator. So, what are the top four things cultivation directors should be discussing with their operations manager right now, as we face an uncertain Summer 2020 and unique COVID-related challenges (product demand uncertainty, reduced workforce, and immediate response to problems and issues):
Operators should be discussing “Who, and what, do I need to operate this facility and how do I make operations more streamlined without diminishing quality, consistency, and yield?”
Efficient operations should focus on labor workflow and circulation and document a clear understanding of how employees will move through the spaces while doing their jobs.
Having a “less labor” philosophy and understanding—a ‘first in and first out’ mentality—drives down cost of production.
By limiting employees’ need to cross paths and segregating processes (e.g. harvest, distro, packaging) in a facility, you can maintain biosecurity and limit the risks of cross-contamination
When working with fewer staff members, everyone should be trained to:
Operate all necessary equipment
Perform keys tasks like nutrient deliver or preventative maintenance
What sort of products do I use to cultivate, process, distribute and how will potential shortages affect my use/cost related to these?
Consider products and supplies that you can order in bulk
Examine and update your chemical regime to focus on products that are cheaper to freight ship, and located within the US or even your state
Mitigate the risk of availability by using products that are have no shelf-life or expiration issues, and those where the supply chain has not yet had disruptions
Automation and technology
What’s the availability to allow for remote monitoring and controls?
Cultivators can take some of the load off the reduced staff by automating critical tasks
Remote monitoring solutions will also allow for faster notification of crop issues
Integrating preventative maintenance tasks like equipment schedules and maintenance can increase efficiency
Ensure that conversations on yield expectations are as transparent as possible and set realistic and achievable goals
Build business models based on the correct numbers that take into account productions numbers on ‘high yield’ genetics versus lower-yielding plants (yield versus price)
Ensure you have a detailed plan that combines both plant density and production goals
Government regulations keep millions of Americans safe every year by controlling what companies can put in their products and the standards those products must meet to be sold to consumers.
Enter the strange case of legal cannabis: In order for cannabis to be legally distributed by licensed medical professionals and businesses, it must be tested. But unlike other consumable goods, cannabis is not regulated by the FDA. Without an overarching federal policy requiring cannabis testing laboratory accreditation, the testing and laboratory requirements differ greatly across state lines.For medical cannabis specifically, accredited testing facilities are especially important.
To be federally regulated, cannabis would first have to be federally legalized. It turns out that states and businesses alike are not willing to wait for a federal mandate. Many states have begun to adopt standards for cannabis testing and some, such as Ohio, have even announced mandatory ISO/IEC 17025 accreditation for all cannabis testing laboratories. As the industry evolves, increased compliance expectations are certain to evolve in tandem.
Some cannabis labs have even taken the initiative to seek ISO/IEC 17025 accreditation of their own volition. Seth Wong, President of TEQ Analytics Laboratories, shared in a press release:
“By achieving ISO/IEC 17025 accreditation, TEQ Analytical Labs believes that we can address the concerns throughout the cannabis industry regarding insufficient and unreliable scientific analysis by providing our clients with State required tests that are accredited by an international standard.”
There are key reasons why accreditation in cannabis testing labs is important. First and foremost, cannabis is a consumable product. Like fruits and vegetables, cannabis is prone to pesticides, fungi and contaminants. The result of putting a potentially hazardous material on the market without proper and documented testing could lead to a public health crisis. An accredited testing lab, however, will ensure that the cannabis products they test are free from harmful contaminants.
For medical cannabis specifically, accredited testing facilities are especially important. Because many consumers of medical cannabis are immuno-compromised (such as in the case of chemotherapy patients), ensuring that products are free from any and all contaminants is critical. Further, in order to accurately determine both short- and long-term effects of prescribed cannabis consumption, accredited and compliant laboratories are necessary.
Accreditation standards like ISO/IEC 17025 also provide confidence that testing is performed properly and to an internationally accepted standard. Rather than returning a “pass/fail” rating on products, the Cannabis Safety Institute reports that an ISO/IEC 17025 laboratory is required to produce numerical accuracy percentages in testing for “at a minimum, cannabinoids, pesticides, microbiology, residual solvents, and water activity.” Reliable data sets that can be reviewed by both accreditors and the public foster trust between producers and consumers.
Finally, ISO/IEC 17025 accreditation demonstrates that a laboratory is properly staffed and trained. The Cannabis Safety Institute’s “Standards for Cannabis Testing Laboratories” explains that conducting proper analytical chemistry on cannabinoids (the chemical compounds extracted from cannabis that alter the brain’s neurotransmitter release) requires personnel who have met specific academic and training credentials. A system to monitor, manage and demonstrate proficiency is necessary to achieve and maintain accreditation. With electronic systems in place, this management and documentation minimizes risk and also minimizes administrative time tracking and maintaining training records.
Following the proper steps of a standardized process is key to improving and growing the cannabis industry in coming yearsFor cannabis testing labs, utilizing a comprehensive software solution to achieve and maintain compliance to standards such as ISO/IEC 17025 is key. Absent of a software solution, the necessary compliance requirements can become a significant burden to the organization. Paper tracking systems and complex spreadsheets open up organizations to the likelihood of errors and ultimately risk.
Because ISO/IEC 17025 has clearly defined expectations for training, a software solution also streamlines the training process while simultaneously documenting proficiency. By utilizing role-based trainings, organizations can be confident employees are receiving proper onboarding and in-service training. Additionally, the effectiveness of training can be proven with reports, which results in smoother audits and assessments.
Following the proper steps of a standardized process is key to improving and growing the cannabis industry in coming years- which means utilizing technology tools such as electronic workflows to ensure proper process controls. Beyond adding critical visibility, workflows also create efficiencies that can eliminate the need to increase staffing as companies expand and grow.
For an industry that is changing at a rapid pace, ensuring traceability, efficient processes and visibility across organizations is paramount. Using a system that enables automation, process control, document management and documented training procedures is a step in the right direction. With the proper software tools in place, cannabis testing labs can achieve compliance goals, demonstrate reliable and relevant results and most importantly ensure consumer safety.
Cannabis testing laboratories around the country are expanding quickly, taking on new clients and growing their business incrementally. Many of these labs are receiving a large number of test requests from growers for potency testing, terpene profiling, pesticide screening, residual solvent screening, heavy metal testing, microbial analysis and even genetic testing. To keep pace with the number of test requests received, efficient data, sample and test management is imperative.
Considering the magnitude of cannabis testing, data management using spreadsheets is a serious impediment to quality assurance. Data being recorded in spreadsheets is error-prone and difficult to manage. Furthermore, using spreadsheets does not allow labs to adhere to regulatory guidelines that demand strict accounting for every gram of the sample, right from reception, consumption for testing, to disposal.
To overcome such data management challenges and improve the operational efficiency of cannabis testing laboratories, a Laboratory Information Management System (LIMS) plays a significant role. LIMS are much more capable than spreadsheets and paper-based tools for managing analytical and operational activities. LIMS enhances the productivity and quality by eliminating the manual data entry. With its built-in audit trail capability, LIMS helps labs adhere to regulatory standards.
LIMS can provide companies with a method to manage samples, records and test results, and ensures regulatory compliance by increasing traceability. LIMS can also be integrated with other lab instrumentation and enterprise systems, enabling easier transmission of information across the lab and the organization, reducing manual efforts and improving decision-making.
Multiple resources are also available to assist labs in preparing for quality assurance and accreditation, LIMS being one of them. LIMS can help cannabis labs with instrument integration, and automate reporting to help improve efficiencies and reduce errors. LIMS, such as CloudLIMS Lite, a cloud-based LIMS, automates cannabis-testing workflows right from sample collection, data recording, managing test chain of custody, sample weight accounting to report generation. With data security and audit trails, a LIMS provides traceable documentary evidence required to achieve ISO 17025 accreditation for highly regulated labs. Above all, cloud-enabled systems are often low in the total cost of acquisition, have maintenance outsourced, and are scalable to help meet the ever-changing business and regulatory compliance needs.
Cloud-based products are secure, easy to deploy and scalable. A cloud product is typically hosted on a server with a guaranteed uptime of 99.5%, allowing for a reliable system, accessible 24×7. Cloud-based LIMS have automatic data backup mechanism that allow for quick turnarounds in case of a server failure or in the eventuality of a natural disaster.
With LIMS in place, cannabis labs can manage sample and requisition-centric records, track sample quantity and location, integrate the test data, and provide online reports to clients. This in turn, reduces the turnaround time for testing and improves the operational efficiency. Besides, audit trail of each and every activity performed by the lab personnel is recorded in the system to ensure that the lab follows regulatory compliance.

On Monday, March 6th, Shimadzu Scientific Instruments, a leading laboratory analytical instrumentation manufacturer, announced the launch of a new product focused on cannabis, according to a press release. Their Cannabis Analyzer for Potency is essentially a high-performance liquid chromatograph (HPLC) packaged with integrated hardware, software, workflows and all the supplies. The supplies include an analytical column, guard columns, mobile phase and a CRM standard mixture.
The instrument is designed to test for 11 cannabinoids in less time and with greater ease than traditional HPLC instruments. In the press release, they claim “operators are now able to produce accurate results with ease, regardless of cannabis testing knowledge or chromatography experience.” One very unique aspect of the instrument is the lack of experience required to run it, according to Bob Clifford, general manager of marketing at Shimadzu. “We have our typical chromatography software [LabSolutions] with an overlay that allows the user to analyze a sample in three simple steps,” says Clifford. Those in the cannabis industry that have a background in plant science, but not analytical chemistry, could run potency analyses on the instrument with minimal training. “This overlay allows ease of use for those not familiar with chromatography software,” says Clifford.
The instrument can determine cannabinoid percentages per dry weight in flower concentrates and edibles. “Once you open the software, it will get the flow rate started, heat the column up and automatically begin to prep for analysis,” says Clifford. Before the analysis begins, information like the sample ID number, sample name, sample weight, extraction volume and dilution volume are entered. After the analysis is complete all the test results are reported for each sample.
Because laboratories wouldn’t have to develop quantitative testing methodology, they argue this instrument would save a lot of time in the lab. “After one day of installation and testing, users are equipped with everything they need to obtain cannabis potency results,” states the press release. According to Clifford, method development for potency analysis in-house can take some labs up to three months. “We can bring this instrument to the lab and have it ready for testing almost immediately,” says Clifford. “The methods for this instrument were developed by a team of twenty scientists working on different platforms at our Innovation Center and was tested for ruggedness, repeatability and quantitative accuracy.”
The instrument’s workflow is designed to meet three methods of analysis depending on testing needs. The High Throughput method package can determine quantities of ten cannabinoids with less than eight minutes per sample. The method was developed in collaboration with commercial testing laboratories. The High Sensitivity method package adds THCV to that target analyte list with ten minutes per analysis. The method provides the sharpest chromatographic peaks and best sensitivity. The High Resolution method package offers full baseline resolution for those 11 cannabinoids in less than 30 minutes per analysis and the ability to add cannabinoids to that target list if regulations change.
The press release states the interface should allow users to reduce the number of steps needed in the analysis and simplify the workflow. The instrument comes with a three-year warranty, preventative maintenance plan and lifetime technical support.
