Interpreting Your Laboratory Data

HPLC Potency Profile
Using High Performance Liquid Chromatography (HPLC), the cannabinoid potency profile gives you the concentration of cannabinoids expressed in percentage of weight per weight (% wt/wt). This is the weight of the cannabinoid divided by the total plant weight. Edibles, tinctures, and topicals are displayed in milligrams of cannabinoids per sample serving size (mg/serving) so patients can better judge their proper dosage levels and compare different medicated products with different serving sizes.

  • %CBG-A is the total concentration of Cannabigerolic Acid.
  • %CBG is the total concentration of Cannabigerol.
  • %CBG-TOTAL is the combined value of CBG-A and CBG.
  • 9-THC-A is the total concentration of Δ9-Tetrahydrocannabinolic Acid.
  • 9-THC is the total concentration of Δ9-Tetrahydrocannabinol.
  • 8-THC is the total concentration of Δ8-Tetrahydrocannabinol.
  • %CBN is the the total concentration of Cannabinol.
  • %THC-TOTAL is the combined value of Δ9-THC-A, Δ9-THC, Δ8-THC, and CBN. Below 9% is considered Low THC Content, while above 14% is considered High THC Content.
  • %CBD-A is the total concentration of Cannabidiolic Acid.
  • %CBD is the total concentration of Cannabidiol.
  • %CBD-TOTAL is the combined value of CBD-A and CBD. Most cannabis strains have been selectively bred for High THC Content, and as such most commonly available cannabis strains have Low CBD Content, below 1%. Above 4% is considered High CBD Content.
  • %CBC is the total concentration of Cannabichromene.
  • %Activated-Total is the combined value of CBG, Δ9-THC, Δ8-THC, CBN, CBD, and CBC, representing the total amount of cannabinoids activated by decarboxylation through storage and consumption (e.g smoking, vaporizing, or cooking).

Moisture Analysis ( %H2O )
This is the weight of the water relative to the total weight of the sample. Laboratory samples are reported in both dry and wet weight. The %H2O of properly cured medicinal cannabis should be between 6-9%. Moisture Analysis needs 24 hours to complete and is required for Potency Profiling.

Foreign Material Inspection
A visual inspection using the latest in digital microscopy technology, we examine the sample in detail, looking for common contaminants such as grey mold, bud rot, spidermites, and other foreign matter. We also inspect the condition and color of the trichromes, which can help determine if the flower was fully mature or harvested early.

Microbial Bioburden Screening
A detailed screen for microbial pathogens is conducted through plate assay, where the number of colony forming units are determined.

GC Multi Solvent Residue Test
Using Headspace Gas Chromatography (GC), the multi-solvent residue test is able to quantify to 10 parts-per-million (ppm) solvents commonly used to extract cannabinoids for concentrates (eg. BHO, CO2, RSO, and Ethanol Cannabis Oil). Solvents tested for include Propane, Isobutane, Butane, Ethanol, Acetone, Isopentane, Pentane, Isopropanol, Hexane, and Naphtha.
