Every assay a compliance panel might ask for, and which labs run it.
01 · Potency
194 labs
Cannabinoid Potency
Quantifies THC, CBD and minor cannabinoids. Required on every compliance panel and on the label of any product sold at retail.
90% OF INDEX
02 · Terpenes
190 labs
Terpene Profile
Identifies and quantifies the aromatic compounds that drive strain character. Usually optional for compliance, but a major marketing input.
88% OF INDEX
03 · Pesticides
191 labs
Pesticide Residue
Screens for regulated pesticide residues at parts-per-billion levels. A failure here is the most common cause of a batch being destroyed.
89% OF INDEX
04 · Mycotoxins
167 labs
Mycotoxins
Detects aflatoxins and ochratoxin A produced by mould. Mandatory in most regulated markets because the toxins survive processing.
78% OF INDEX
05 · Heavy metals
181 labs
Heavy Metals
Measures lead, arsenic, cadmium and mercury. Cannabis is a hyperaccumulator, so contaminated soil shows up in the finished product.
84% OF INDEX
06 · Microbials
193 labs
Microbial Contaminants
Screens for total yeast and mould, coliforms, E. coli, salmonella and Aspergillus species. Required before any product reaches a patient.
90% OF INDEX
07 · Residual solvents
183 labs
Residual Solvents
Confirms that butane, ethanol, propane and other extraction solvents have been purged below action limits. Applies to concentrates and vapes.
85% OF INDEX
08 · Moisture / Aw
131 labs
Moisture & Water Activity
Water activity above roughly 0.65 Aw lets mould grow in the package. Cheap to run and the single best predictor of shelf-life failure.
61% OF INDEX
09 · Stability
37 labs
Stability & Shelf Life
Repeat testing across a storage window to establish an expiry date and prove potency claims hold over time.

Cannabis Terpene Testing - The Simple Explanation
There have been over 100 different terpenes discovered so far and it seems every strain has a unique composition of them. Terpenes are produced inside structures called glandular trichomes, which also produce cannabinoids. These compounds are found in almost every plant and are responsible for the pleasant aromas that can be found in cannabis. The different terpene compositions in each strain are what give unique flavors, aromas, and colors to the cannabis plant. Environmental conditions such as the climate, fertilizer used, soil type, and the age of the plant can play a huge role in terpene development. For example, prior to aging, terpenes are mostly found in high concentrations in unfertilized female plants.
