ANAB provides accreditation for laboratories that do analytical testing of cannabis and cannabis-derived products, including oils, edibles, drinks, concentrates, flowers, butters, and waxes, and hemp and products derived from hemp.

Testing of cannabis products is necessary to demonstrate that they are safe for consumption and free from harmful levels of contaminants and adulterants. 

ANAB accredits cannabis testing laboratories to ISO/IEC 17025 for a variety of relevant tests, including:

  • Cannabinoid testing and content (e.g., THC, THCV, CBD, CBDV, CBG, CBC, and CBN)
  • Terpene profile 
  • Pesticides, fungicides/plant growth regulators 
  • Microbiological contaminants  such as mold, insects, and bacteria
  • Residual solvents

Demand for testing laboratories is growing as many states have legalized medical marijuana and some have implemented specific mandates for testing protocols. ANAB can accredit your lab to meet regulatory and state specific requirements.
