EVIO Labs recently became the first cannabis laboratory in Florida to obtain ISO 17025 accreditation. Perry Johnson Laboratory Accreditation, Inc. (PJLA), an organization that provides third-party assessments to ISO/IEC 17025, accredited EVIO Labs. The assessment process that lead to ISO 17025 accreditation for EVIO Labs included a thorough review of their quality management system, their capability to perform potency and contaminant testing for cannabis products.
Tracy Szerszen, president and operations manager at PJLA, encourages this international standard for laboratories to provide confidence to end-users that the test results they receive are reliable. She says laboratories that achieve this accreditation are showing they have the proper tools, equipment and staff to provide accurate testing. “It is a very critical component of the industry, and becoming accredited provides the assurance that laboratories are performing to the highest standard,” says Szerszen. “EVIO Labs has taken the right step in their commitment towards meeting this standard and providing clean and safe cannabis for the patients of Florida.”
EVIO Labs provides cannabis testing for cannabinoid and terpene profiles, microbiological and pesticides contamination, residual solvent, heavy metals, mycotoxins, water activity and moisture content. Chris Martinez, co-founder and president of EVIO Labs Florida explains that the Florida Department of Health mandates that an independent third-party laboratory tests medical cannabis to ensure that these products are safe for human consumption. Martinez says their first priority is the safety of their patients, and ensuring that EVIO Labs provides clean and safe cannabis for Florida.
Martinez launched their laboratory with some help from Shimadzu last year. “Our Broward lab is powered by Shimadzu with over $1.2M in the latest testing equipment utilizing LCMS technology with the world’s fastest polarity switching time of 5 m/sec and scan speeds of 30,000 u/sec with UF Qarray sensitivity 90 times that of previously available technologies,” says Martinez. According to Martinez, their licensing agreement with EVIO Labs (OTC:SGBYD) marked a first for the publicly traded company with exclusivity in the Florida market. The agreement includes proprietary testing methodologies, operating procedures, training and support.
Every certificate of analysis is reviewed by a lab director with over 20 years of experience operating in FDA regulated labs. Martinez says that EVIO has some of the most advanced technology in the industry, which provides them the opportunity to quickly provide results, frequently as fast as a 24-hour period. Martinez and his team are currently building a 3,300 square-foot laboratory in Gainesville, which is expected to be running by March of this year.
In the first part of this series, we spoke with Michelle Bradac, senior accreditation officer at A2LA, to learn the basics of cannabis laboratory accreditation. In the second part, we sat down with Roger Brauninger, A2LA Biosafety Program manager, to learn why states are looking to lab accreditation in their regulations for the cannabis industry. In the third part, we heard from Michael DeGregorio, chief executive officer of Konocti Analytics, Inc., discussing method development in the cannabis testing industry and his experience with getting accredited.
In the fourth and final part of this series, we sit down with Susan Audino, Ph.D., an A2LA lead assessor and instructor, laboratory consultant and board member for the Center for Research on Environmental Medicine in Maryland. Dr. Audino will share some insights into method validation and the most technical aspects of laboratory accreditation.
Susan Audino obtained her Ph.D. in Chemistry with an analytical chemistry major, physical and biochemistry minor areas. She currently owns and operates a consulting firm to service chemical and biological laboratories. Susan has been studying the chemistry and applications of cannabinoids and provides scientific and technical guidance to cannabis dispensaries, testing laboratories and medical personnel. Dr. Audino’s interest most directly involves cannabis consumer safety and protection, and promotes active research towards the development of official test methods specifically for the cannabis industry, and to advocate appropriate clinical research. In addition to serving on Expert Review Panels, she is also chairing the first Cannabis Advisory Panel and working group with AOAC International, is a member of the Executive Committee of the ASTM Cannabis Section and has consulted to numerous cannabis laboratories and state regulatory bodies.
CannabisIndustryJournal: What are the some of the most significant technical issues facing an accreditation body when assessing a cannabis-testing laboratory?
Susan: From the AB perspective, there needs to be a high level of expertise to evaluate the merits and scientific soundness of laboratory-developed analytical test methods. Because there are presently no standard or consensus test methods available, laboratories are required to develop their own methods, which need to be valid. Validating methods require a rigorous series of tests and statistical analyses to ensure the correctness and reliability of the laboratory’s product, which is– the test report.
CIJ: When is method validation required and how does this differ from system suitability?
Susan: Method validation is required whenever the laboratory modifies a currently accepted consensus or standard test method, or when the laboratory develops its own method. Method validation is characterized by a series of analytical performance criteria including determinations of accuracy, precision, linearity, specification, limit of detection, and limit of quantitation. The determination of system suitability requires a series of deliberate variations of parameters to ensure the complete system, that is all instrument(s) as well as the analytical method, is maintained throughout the entire analytical process. Traditionally, method validation has been referred to as “ruggedness” and system suitability as “robustness.”
CIJ: What are the most important aspects of method validation that must be taken into account?
Susan: In keeping with the FDA guidelines and other accepted criteria, I tend to recommend the International Conference on Harmonization (ICH), particularly Q 2A, which is a widely recognized program that discusses the pertinent characteristics of method validation. This include: method specification, linearity, range, accuracy, and precision (e.g., repeatability, intermediate precision, reproducibility). As mentioned earlier, system suitability is also a critical element and although related to method validation, does require its own protocol.
CIJ: What three areas do you see the laboratory having the hardest time with in preparing for accreditation?
Susan: My responses to this question assume the laboratory employs appropriate instruments to perform the necessary analyses, and that the laboratory employs personnel with experience and knowledge appropriate to develop test methods and interpret test results.
By and large, method validation that is not appropriate to the scope of their intended work. Driving this is an overall lack of information about method validation. Oftentimes there is an assumption that multiple recoveries of CRMs constitute “validation”. While it may be one element, this only demonstrates the instrument’s suitability. My recommendation is to utilize any one of a number of good single laboratory validation protocols. Options include, but are not limited to AOAC International, American Chemical Society, ASTM, and ICH protocols.
Second is the lack of statistically sound sampling protocols for those laboratories that are mandated by their governing states to go to the field to sample the product from required batches. Sampling protocols needs to address the heterogeneity of the plant, defining the batch, and determining/collecting a sample of sufficient quantity that will be both large enough and representative of the population, and to provide the laboratory an adequate amount from which to sub-sample.
Third, sample preparation. This is somewhat intertwined with my previous point. Once an appropriate sample has been collected, preparation must be relevant to the appropriate technology and assay. It is unlikely that a laboratory can perform a single preparation that is amenable to comprehensive testing.
In the first part of this series, we spoke with Michelle Bradac, senior accreditation officer at A2LA, to learn the basics of cannabis laboratory accreditation. In the second part, we sat down with Roger Brauninger, A2LA Biosafety Program manager, to learn why states are looking to lab accreditation in their regulations for the cannabis industry.
In the third part of this series, we sit down with Michael DeGregorio, chief executive officer of Konocti Analytics, Inc., to talk method development in the cannabis testing industry and his experience with getting accredited. In the final part of this series, we are going to sit down with Susan Audino, an instructor at A2LA to learn more about the requirements where she’ll offer some advice for labs seeking accreditation.
Michael DeGregorio is a doctor of pharmacy with an extensive career in medicine and scientific research. He’s worked in cancer research and medicine, teaching at the University of California, San Francisco, Yale University School of Medicine, University of Texas, Health Science Center at San Antonio and University of California, Davis. Before becoming the CEO of Konocti Analytics, a laboratory based in California, DeGregorio was also a published author in a large number of peer-reviewed medical journals.
In this piece, we sit down with DeGregorio to find out what challenges labs face when getting accredited, why they sought accreditation and their experience with getting off the ground. Stay tuned for the final part of this series!
CannabisIndustryJournal: How does a laboratory go about choosing an appropriate method in an industry where, generally, there are no validated methods available?
Michael DeGregorio: Our approach to developing analytical methods for testing cannabis began with a review of the existing laboratories and their methods, where we found no standardization and inconsistent results. Since cannabis is being used by the public and as a medicine, our goal is to help make it as contaminant-free as possible for the well-being of the consumer, and this begins by developing a state-of-the-art analytical facility.
When developing new methods, we review the published literature to see what has already been done and try to arrive at a scientifically sound consensus. We then perform experiments to determine which set of conditions works best for us. Once we have developed an appropriate method, we validate it pursuant to ISO/IEC 17025 requirements.
CIJ: How do you go about choosing what type of equipment to use for testing (e.g. by limit of detection, acceptable method use of equipment for other industries, etc.)?
Michael: After reviewing the operations of other testing laboratories, we concluded that, in general, they were not taking advantage of the most advanced technologies and had limited personnel qualified to operate it. Because public safety is our main concern, we chose state-of-the-art equipment, including GC/LC-MS with Orbitrap and ICP-MS, for testing medicinal cannabis. In addition to identifying unknown pesticides, we needed the capability of performing full chemical screening of all samples for potentially harmful compounds, e.g. steroids, present in cannabis, as well as the ability to detect trace levels of metals.
Our greatest concern is the fact that pesticides in cannabis have not been adequately studied. Current pesticide regulations suggest that government authorities believe that there are a finite number of pesticides available. Smart farmers could easily avoid the pesticides on current lists. Because of this, we chose to validate our pesticide methods with a focus on chemical classes, as opposed to specific pesticides, to give us the broadest possible coverage of potential compounds. The Orbitrap mass spectrometers also allow us to detect and identify unknown pesticides. This is something not currently being done by other laboratories. The latest microbiology methods for cannabis testing include DNA analysis, and for this we use qRT-PCR technology. Finally, the high sensitivity of ICP-MS allows for the detection of metals concentrations that may be harmful, yet undetectable by other means.
CIJ: What do you feel are the benefits of being accredited?
Michael: Being accredited shows the public that we have made a commitment to quality analytics. We feel this gives our clients peace of mind when marketing their products, knowing that they have been tested by a laboratory meeting the highest international standards of operation available using the latest technology. Furthermore, being accredited requires participation in ongoing proficiency testing programs, which helps maintain analytical competency. It should be pointed out that any prospective client of an analytical facility should take into account the laboratory’s full accredited scope of testing to ensure its competency.
CIJ: What challenges did you face during the process of getting your laboratory started and/or during the accreditation process?
Michael: Developing the quality management system and getting our equipment and processes to a state where they met accreditation requirements took several months of hard work, and turned out to be a bit more daunting than we anticipated. Our pre-accreditation assessment revealed that much work remained to be done, and it gave us a real appreciation for the level of detail and documentation required. We remained determined and eventually achieved our accreditation.
CIJ: What are the benefits to the grower and dispensaries to choosing an accredited laboratory for the testing of their product?
Michael: By choosing an accredited laboratory with a full scope of testing (potency, pesticides, mycotoxins, metals, microbiology, residual solvents and terpenes), growers and dispensaries can rest assured that their products have been tested using validated methods with appropriate quality control by trained, competent personnel. For growers, this makes their products more attractive to potential buyers. For dispensaries, this means they can confidently market their products with the knowledge that the information shown on the label is accurate, which in turn gives their customers peace of mind that the product they are consuming does not contain unacceptable levels of contaminants.
CIJ: Why did you choose A2LA?
Michael: Once we decided to pursue accreditation, we researched the various accrediting bodies available as well as their reputations. We discovered that while all accrediting bodies are themselves accredited to the same standard, accreditation by the various bodies was not considered equal in practice. In our opinion, A2LA was considered the most prestigious, highly regarded accrediting body. Furthermore, some of the most prestigious laboratories in the country are accredited by A2LA, including Los Alamos National Laboratory, the Food and Drug Administration’s Center for Biologics Evaluation and Research, Lawrence Livermore National Laboratory, Centers for Disease Control, Federal Bureau of Investigation and the United States Department of Agriculture. Many of our preferred sources of scientific supplies and services are accredited by A2LA as well. As our goal was to be accredited by the best available accrediting body, we chose A2LA.
In the first part of this series, Michelle Bradac, senior accreditation officer at the American Association for Laboratory Accreditation (A2LA), told us about the basics of laboratory accreditation, what it means and why it is such a cornerstone of product safety. In this next piece, we sit down with Roger Brauninger, A2LA Biosafety Program manager, to learn why states are looking to lab accreditation in their regulations for the cannabis industry.
Brauninger has worked at A2LA since 1999. As the manager of their biosafety program, his focus is on developing and maintaining accreditation programs in the life sciences. Brauninger has conducted a number of management system assessments to ISO/IEC 17025 and 17020 and also evaluates other assessors in this role.
He is A2LA’s point person for interacting with organizations working with food and drug safety, human and animal anti-doping, biological and chemical threat agents and since 2014 for issues related to cannabis testing. He is a member of the ASTM D37 Cannabis committee, a group focused on creating standards for cannabis products. He was also a member of the stakeholder panel on strategic food analytical methods (SPSFAM) cannabis potency working group when they were awarded the Official Methods Board (OMB) award for achievement in technical and scientific excellence at the AOAC’s Annual Meeting and Exposition in Atlanta, GA. Brauninger holds an M.S. degree in Cellular, Microbial and Molecular Biology from George Mason University and is a member of the Society for Toxicology, AOAC International and the International Association for Food Protection (IAFP).
In this part of the series, we sit down with Brauninger to learn specific requirements in states, some of the benefits of using ISO/IEC 17025 and the influx of start-up or novice testing laboratories. Stay tuned for part three.
CannabisIndustryJournal: Do all states with legalized medical cannabis require the testing to be performed by an ISO/IEC 17025 accredited laboratory?
Roger Brauninger: No not at present, while most of the states where cannabis is legal do require accreditation; there are some states that have no requirements dealing with ensuring the competence of the testing laboratories, some that require the labs to be accredited to state environmental and drinking water standards, some that require laboratories adhere to Good Laboratory Practices (GLP) requirements and some have no requirements in place currently. Now, there are roughly 13 states that require or recommend accreditation of the testing laboratory to ISO/IEC 17025.
CIJ: If and when cannabis use is accepted federally, how is ISO/IEC 17025 accreditation of testing laboratories beneficial?
Roger: The accreditation process provides a uniform platform to allow for comparability of test results between states. This would also allow for these laboratories to benefit by being able to expand their customer base, if state borders were not an artificially imposed barrier to trade. This could also help to raise the quality of the testing services by allowing for greater participation in realistic accredited proficiency testing programs, which can create greater comparability of methods and results.
CIJ: What are the benefits to the states by choosing to require ISO/IEC 17025 accreditation as a basis for competence of testing laboratories?
Roger: States face the unique challenge, due to the federal illegality of cannabis, that they must craft their own regulatory cannabis program requirements. The ISO/IEC 17025 requirements provides a means upon which to recognize laboratory competence. This saves the states from having to come up with their own laboratory quality management requirements detailing the necessary activities a laboratory must address with respect to documentation, chain of custody, method validation, etc. Because these items are already considered in the standard. ISO/IEC 17025 helps to creates a baseline consistency amongst laboratories between states. And It also helps to provides for the legal defensibility of the test results. If and when cannabis is legalized on a federal level, a uniform 50 state recognition is possible using ISO/IEC 17025 as the basis of recognition. In short accreditation can help to ensure that test results have greater comparability and reliability; It also provides greater trust and confidence in the labels and the stated ingredients.
CIJ: Many of the laboratories are “starting up”, how is A2LA equipped to deal with the influx of novice laboratories in this field of testing?
Roger: A2LA offers many different relevant training classes, including those on the ISO/IEC 17025 standard itself, (as well as ones that also contain cannabis-specific content), internal auditing, documenting your quality system, etc. for the laboratories. A2LA also is knowledgeable regarding various states’ cannabis regulatory requirements and can help guide the labs through some of the many obstacles they face in order to perform testing in their state.
CIJ: Does A2LA provide any technical assistance to laboratories that are starting up in this industry?
Roger: A2LA has numerous technical assessors who are experts in the analytical technology associated with cannabis testing. Assessors can be hired in a consulting role and act independently of the assessment process (and independent of A2LA). As a consultant, they can also assist in setting up a quality management system in compliance with ISO/IEC 17025.
CIJ: What benefits can be gained from a laboratory seeking accreditation or from a state that requires cannabis testing laboratories to be accredited?
Roger: Accreditation can provide legal defensibility and increased confidence in the test results being able to stand up in court. It also may help to lower the cost of doing business because it helps to ensure that the test methods are in control by the laboratory and has been shown to be able to reduce the need for repeat testing. Laboratory accreditation has also led to reduced insurance rates in some cases.
Earlier this week, SC Labs issued a press release announcing they achieved ISO/IEC 17025:2005 accreditation for the cannabinoids panel at their Santa Cruz location.
“We are thrilled to announce our ISO accreditation as this is one of our most important achievements over the past seven years of serving the cannabis industry and demonstrates our commitment to serving our clients with integrity,” says Jeff Gray, co-founder and chief executive officer of SC Labs. ISO 17025 accreditation represents an international standard for a laboratory’s technical competence in producing accurate test results.
“Being accredited to this International Standard demonstrates our robust quality system, technical competence, the calibration and suitability of our instrumentation and our ability to produce precise and accurate test data,” says Gray. “For clients, it enhances their confidence in our services and their choice in a business partner, provides them with additional legal defensibility in complying with upcoming regulations, and enhances the integrity of their products based on SC Labs results.”
SC Labs is currently expanding in California, growing their Southern California and Santa Cruz locations, and adding field offices throughout the state, according to the press release.
The lab was accredited to ISO/IEC 17025 – General Requirements for the Competence of Testing and Calibration Laboratories, so they are now able to test for pesticides in cannabis and other matrices, according to the press release published today. “WSDA sought this accreditation to ensure our clients can have absolute confidence in our testing methods and lab results. The information we produce drives enforcement cases and policy decisions,” says Mike Firman, manager of the WSDA Chemical and Hop Laboratory. “We want to do everything that can be done to make sure our data is reliable.”
The A2LA Cannabis Accreditation Program is essentially a set of standards for quality in testing cannabis and cannabis-based products, such as infused products, tinctures and concentrates. ISO 17025 accreditation is quickly become a desirable certification for laboratories. Many states strongly encourage or even require ISO 17025 accreditation for cannabis laboratories. California recently released a set of proposed lab testing regulations for the cannabis industry that specifically requires an ISO 17025 accreditation in order for laboratories to issue certificates of analysis.
Because each state’s requirements for laboratories testing cannabis varies so greatly, A2LA works with state regulators to craft their accreditation program to meet each state’s specific requirements. “A2LA is excited to play such an important role in the accreditation of cannabis testing laboratories and is pleased to see ISO/IEC 17025 accreditation expanding into additional states,” says A2LA General Manager Adam Gouker. “Priority must be placed on ensuring that cannabis products are tested by competent laboratories to convey confidence in the results – a cornerstone which underpins the safety to all end-users.” A2LA is currently accepting applications for cannabis laboratories working to receive accreditation. Labs that already have ISO 17025 accreditation and are in a state with legal cannabis, have the ability to expand their scope of accreditation if they are looking to get into cannabis testing.
