Cannabinoid Analysis

Cannabinoids are a diverse class of compounds known as the active ingredients in cannabis. Therapeutic Health Choice applies high-pressure liquid chromatography diode array detection (HPLC-DAD) for the analysis of 10 of the most prevalent cannabinoids including:

  • Delta(8)
  • Delta(9)- Tetrahydrocannabinol (Δ9-THC)
  • Delta(9)- Tetrahydrocannabinolic acid (Δ9-THCA)
  • Cannabidiol (CBD)
  • Cannabidolic acid (CBDA)
  • Cannabidivarin (CBDV)
  • Cannabigerol (CBG)
  • Cannabigerol acid (CBGA)
  • Cannabichromene (CBC)
  • Cannabinol (CBN)
  • THCV
  • THCVa
  • CBL

Our potency technique is validated to extract 100% of cannabinoids. THC uses an (AOAC 2018:11) Validated Method.

Microbial Analysis
What we test

PCR – Utilizing the AOAC validated bioMerieux platform.

  • STEC
  • Aspergillus
  • Salmonella


  • Total Coliform
  • Total Yeast and Mold
  • Salmonella

THC’s Microbial Screening uses only compendial methods. THC has three dedicated microbial laboratory rooms to prevent cross contamination.

Heavy Metals

Cannabis, just like any plant, can bioaccumulate heavy metals like mercury. These heavy metals can build up in the body and cause harmful effects. Therapeutic Health Choice’s uniquely automated sample preparation platform, along with an analysis by inductive coupled plasma – mass spectrometry (ICP-MS) ensures optimal recovery and detection.

What we test
  • Cadmium
  • Lead
  • Mercury
  • Arsenic
  • Nickel
  • Chromium
  • Copper (extracts and concentrates)
Filth and Foreign Material, Water Activity, and Vitamin E Acetate
What we test

Filth and Foreign Material

Microscopic analysis to ensure the absence of non-marijuana material. Marijuana is dissected and examined for material such as glass and metal fragments, mildews and molds, insects, and mammalian excrement.

Water Activity

Water activity measures the water of the product that is available for microbial growth. This assay ensures that the product will not be able to grow mold, mildew or bacteria.

Vitamin E Acetate

Vitamin E Acetate is a cheap thinning agent used to adjust the thickness of CBD or THC vape concentrates. According to the United States Center for Disease Control and Prevention (CDC), vitamin E acetate is considered to be a threat consumer safety. Here at THC, we ensure that vape concentrates are free from vitamin E acetate. (UHPLC)

Chemical Residue Testing

The detection of chemical residues (insecticides, fungicides and plant growth regulators) is crucial to producing the safest products. Our state-of-the-art liquid chromatography – mass spectrometry GC-MS|MS analysis detects all 58 banned chemicals in the State of Michigan.

Residual Solvents

Solvents are commonly used in production of cannabis concentrates and extracts. These solvents are typically removed in production but can present a danger to consumer’s health if too much is left in the final product. Therefore, residual solvent testing is necessary to ensure the product is safe for consumption. (GC/MS)

Residual Solvents

Terpene Profile

Terpenes are naturally occurring compounds that provide flavor and aroma. In conjunction with cannabinoids, they are believed to enhance both the physiological and cerebral effects felt by the user. The synergy between terpenes and cannabinoids, commonly known as the “entourage effect” is the reason terpene testing has become critical to both producers and consumers. For that reason, here at THC, we test for 37 different terpenes. (GC/MS direct injection)
