Cannabis Testing

What We Test

A diverse line-up of instrumentation allows us to use the most appropriate method for the sample matrix, and allows us to test a vast array of cannabis related products.  We can test cured flowers, concentrates (including BHO, CO2 Oil and other solvent extracts, wax, hash, keif, etc.), edibles, or "Medibles" (such as chocolate, cooking oil, candies, baked goods, and beverages), topicals, and tinctures. Glycerin-based products are also welcome. If you have a unique product or product line, please contact us to discuss your needs. 

What We Test For

Our assays have been carefully developed with HB 3460 compliance in mind.  Our Full Compliance testing suite offers everything a dispensary needs to stay compliant with State testing laws, as well as ensure the safety of consumers and the quality of products on the shelf.  Our testing methods are based on relevant industry standards that have been approved by AOAC, AHP, UNODC, USP, EPA and FDA for testing agricultural commodities meant for human consumption.

We test for:

  • Cannabinoid Potency (Δ9THC, THCA, CBDA, CBD, CBN)
  • Microbiological Contaminants, such as mold/mildew and yeast
  • Pesticides/Fungicides (exceeds compliance with State regulations)
  • Terpenes – 37 Compound Screen
  • Residual Solvents – 43 Compound Screen (Full M91 List)
  • THC: CBD Ratio in Early Leaf Material - Find out if your young plants are high CBD producing strains.
  • Early Sex Determination - reduce overhead on seedling cultivation (in partnership with Phylos Bioscience)
  • Genetic Mapping - is your strain really what you think it is? (Coming Soon! In partnership with Phylos Bioscience)


How We Test

In designing our lab, we’ve taken AOAC (Association of Official Analytical Chemists), AHP (American Herbal Pharmacopeia), FDA, ODA (Oregon Department of Agriculture), NELAC (National Environmental Laboratory Accreditation Conference) and ISO (International Organization for Standardization) 17025:2005 very seriously. Every good lab should be able to stand up to scientific scrutiny, and stand behind the methods they’ve chosen to conduct their testing. Laboratory accreditation often takes almost 2 years to accomplish, and we met our goal to be ORELAP accredited to The NELAC Institute standard in September of 2016. The standards approved by all of the above organizations are a foundation of Oregon Growers Analytical. We know how to get it done right, and we’re not cutting any corners.

When evaluating a third party lab, it’s important to ask about methods, instrumentation, and Standard Operating Procedures. We’ve chosen our instrumentation carefully based on the commodities and compounds we’re testing. Cannabis has many active compounds: there are over 100 cannabinoids, 120+ terpenes, and 29 flavonoids that we know of today. Many cannabinoids are heat sensitive, changing under high temperatures to re-form as other cannabinoids. This also applies to pesticides and fungicides.

There are two types of instrumentation that are qualified for testing cannabinoid potency: Gas Chromatography (GC) and High Performance Liquid Chromatography (HPLC). Since a gas chromatograph uses heat during the analytical process, it’s unable to accurately quantify many of the compounds found in cannabis. This is why we’ve chosen HPLC as our primary analytical instrument for testing cannabinoids and pesticides.
