Every assay a compliance panel might ask for, and which labs run it.
01 · Potency
171 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
167 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
168 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.
88% OF INDEX
04 · Mycotoxins
148 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
158 labs
Heavy Metals
Measures lead, arsenic, cadmium and mercury. Cannabis is a hyperaccumulator, so contaminated soil shows up in the finished product.
83% OF INDEX
06 · Microbials
169 labs
Microbial Contaminants
Screens for total yeast and mould, coliforms, E. coli, salmonella and Aspergillus species. Required before any product reaches a patient.
89% OF INDEX
07 · Residual solvents
159 labs
Residual Solvents
Confirms that butane, ethanol, propane and other extraction solvents have been purged below action limits. Applies to concentrates and vapes.
84% OF INDEX
08 · Moisture / Aw
116 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
36 labs
Stability & Shelf Life
Repeat testing across a storage window to establish an expiry date and prove potency claims hold over time.

Cannabis Lab 101: Cannabis Testing Instruments — HPLC, GC-MS, ICP-MS, and What Each One Is For
I spent four-plus years running compliance assays on a bench, and the question I heard most from new techs was simple: which box does which test? This walkthrough covers every major instrument class in a cannabis testing lab — what it detects, why it was chosen for that assay, and the one mistake buyers keep making.

Cannabis Lab 101: Non-Laboratory Cannabis Testing — What Handheld and Benchtop Devices Can and Cannot Tell You
I spent four years running potency assays on a benchtop HPLC, and I still get asked whether a handheld NIR or a TLC spot kit can replace a lab result. Here is an honest breakdown of what each device class actually measures, where the published accuracy data land, and why none of them count as compliance tests.

Cannabis Lab 101: The Cannabis Testing Market in 2026 — Who Tests What, and What It Costs
I spent four years on the bench watching growers squint at invoices and ask why a flower panel costs $600. This article breaks down who is licensed to test cannabis, what analytes every compliance panel must cover, what real labs charge per test, and why a single national market-size number is harder to find than it looks.
One brief. Every lab that fits.
