Cannabis Testing Laboratory Accreditation Program

A2LA offers accreditation to laboratories performing analytical testing of cannabis and cannabis-derived products, such as flowers, concentrates, butters/waxes, drinks, tinctures, oils and edibles, as well as hemp and hemp-derived products.

Appropriate testing is critical to demonstrate that these products do not contain harmful levels of contaminants or adulterants and are safe for public consumption. 

Specific testing may include, but is not limited to, the following: 

  • Cannabinoid testing and content (CBC, CBD, CBDa, CBG, CBN, THC, THCa, THCv, etc.) 
  • Terpene profile 
  • Pesticides/fungicides/plant growth regulators 
  • Residual solvents 
  • Heavy metals 
  • Microbiological contaminants (mold, insects, bacteria, etc.) 

Confidence in the laboratories that perform this testing, and assurance in the test results, is possible through accreditation to the ISO/IEC 17025 standard. The ISO/IEC 17025 standard is non-prescriptive and flexible, allowing the organization maximum flexibility in determining what works best for their business needs. 

Program Requirements

Cannabis testing laboratories may select one of two tracks for A2LA accreditation. The accreditation tracks both provide independent, third-party accreditation assessments crafted to serve both the medical cannabis and recreational adult-use markets. These tracks are as follows:

  • ISO/IEC 17025 as the primary framework, along with any additional, state-specific requirements
  • ISO/IEC 17025 and the additional accreditation requirements derived from the Americans for Safe Access (ASA) Patient Focused Certification (PFC) Program for testing laboratories

The PFC Laboratory Operations requirements are constructed in accordance with the Recommendations to Regulators for Cannabis Operations, a guide developed by the Cannabis Committee for the American Herbal Products Association (AHPA). An assessment to these additional requirements is voluntary. They include security, personnel training, sample receipt, chain of custody, handling and disposal, and data review. 

Please contact us for more information on specific state requirements for testing to determine the minimum cannabis testing required.
