Additional testing information

When submitting samples for testing, we’ll ask you for information about the sample(s) you’re submitting, such as what tests you’d like performed, the sample or serving size, and the cultivar name or genetic parentage of the product. It is not a problem if you don’t know the strain/cultivar as this info is not critical to any of the testing processes. All information collected during a sample drop off is kept strictly confidential, and we are happy to answer any and all questions you may have about the testing process, pricing, and amount of product required for each test.

Results are available online, however, your results will not be publicly visible unless you provide consent for them to be listed on our Tested Products page.

We offer ISO accredited testing services for flower, extracts, concentrates, and marijuana-infused products (MIPs) such as edibles, lotions, tinctures, drinks etc. We currently provide potency testing that includes cannabinoid and terpene profiles, as well as safety screening for the presence of heavy metals, pesticides, residual solvents, microbiological contamination, and mycotoxins. For more information about the different tests, please review our Services page.
