Ask the Experts: Ensuring the Validity of Cannabis Lab Testing



Hashish screening laboratories are a single of the main players in the business for shielding general public wellbeing. Making sure that laboratory take a look at results are trustworthy and legitimate requires a multipronged method involving process validation, proficiency screening and accomplishing recurrent assessments of equipment and procedures.

Hashish screening laboratories generally use a assortment of different methods to carry out proficiency tests. Laboratories can possibly take part in programs run by ISO/IEC 17043-accedited proficiency testing vendors or via intralaboratory comparison. Evaluating distinctive instruments, solutions, systems versus pre-outlined criteria is a will have to when validating techniques for a specific type of check and making sure the competence of the laboratory.

Over and above proficiency testing, there are a amount of other stopgaps at a laboratory’s disposal for making certain valid benefits, like applying accredited certified reference resources, executing checks on measuring gear often, examining documented results and retesting retained items. All of that and far more is outlined in the ISO/IEC 17025:2017 regular, section 7.7.

What great is a check final result if you are not able to attest to its validity?

There is a ton that goes into generating sure laboratories deliver valid outcomes, much of which is specific in the accreditation procedure. For more data, we sit down with Keith Klemm, senior accreditation manager for ANSI National Accreditation Board to master about laboratory accreditation, system validation and other certifications and credentialing readily available in the cannabis industry.

Q: Why is system validation essential for hashish test methods? 

Keith Klemm: Because hashish production, tests, and revenue is controlled by just about every person condition, there are incredibly couple of typical strategies for testing cannabis and hashish-derived products. Non-common techniques or solutions created by the laboratory have to be validated to be certain the techniques are fit for their meant purpose. What good is a check final result if you can not attest to its validity? There would be no self confidence that the final results are precise. Additionally, when companies these as ISO, AOAC and ASTM are creating common procedures for use in the laboratory, the vast vary of products and solutions and matrices currently being tested involve modifications to standard solutions. Common methods employed outside their intended scope should also be validated, again to ensure the approach remains in good shape for the meant reason.

Q: We’re really familiar with laboratory accreditation. What other accreditations are obtainable in the hashish business?

Klemm: Accreditation packages are readily available for product certification and staff credentialing, in addition to laboratory accreditation. ANAB’s item certification system was launched in 2020 and is dependent on the prerequisites of ISO/IEC 17065. The plan combines the requirements of this conventional with precise plan requirements to attest to the competency of certification bodies who then certify solutions inside the plan. Two strategies are in enhancement distinct to the cannabis field: Hashish Security and Excellent (CSQ) and PurityIQ. For staff credentialing, a new Hashish Certification Accreditation Method (C-CAP) was produced and is primarily based on ASTM D8403, Common Follow for Certification Systems within the Cannabis and Hemp Industries. It also consists of any supplemental condition Responsible Vendor Schooling needs.

Q: What are the ways to starting to be an accredited cannabis screening laboratory, products certification physique, or C-CAP firm?

Klemm: The course of action begins with a request for estimate. The corporation prepares for the initial evaluation by applying the specifications of the applicable expectations, regulatory prerequisites, and scheme specifications. ANAB believes in a partnership solution to accreditation with a focus on client requirements even though guaranteeing accreditation specifications are satisfied. When the group is prepared, an preliminary doc assessment is performed. The accreditation evaluation is then carried out on-web site by technically qualified and proficient assessors. If any nonconformities are encountered, the firm provides a reaction with induce and corrective actions. As soon as all nonconformities are solved and technological review is completed, a scope of accreditation and certification are offered to the corporation. The technological overview may perhaps range based on the accreditation that is being sought, but the typical process of accreditation is the same. Immediately after accreditation is realized, the corporation moves into a cycle of surveillance and reassessment as defined by the accreditation software and any plan necessities.
