How to Read a Cannabis Lab Result

A cannabis lab certificate of analysis (COA) is a structured document with seven sections: identity, cannabinoid panel, terpene profile, pesticide screen, residual solvents, heavy metals, and microbial. Reading each section takes thirty seconds and tells you exactly what is in the cart.

01

Identity

The top of the COA names the brand, batch ID, strain, production date, test date, and the lab that ran the analysis. Match each to your package. Mismatches signal counterfeit.
02

Cannabinoid panel

Total cannabinoids percentage, broken down by THCA, THC, CBD, CBG, CBN, and minor cannabinoids. Live resin typically reads 75 to 90 percent total. Live diamonds 90 to 94 percent. Distillate 90 percent plus on THC alone.
03

Terpene profile

Total terpene percentage with each terpene listed by name and percentage. The top three terpenes are the dominant flavor and effect drivers. Compare to the strain's published terpene wheel.
04

Pesticide screen

Pass or fail per pesticide tested. California requires a defined pesticide list. Top-shelf brands test the full list at low-detection thresholds. Waxx publishes pass for every pesticide tested.
05

Residual solvents

Pass or fail per solvent. Hydrocarbon extraction uses solvents (typically butane and propane), and post-extraction purging removes them. The COA should show pass at low-detection thresholds.
06

Heavy metals

Pass or fail per metal (lead, arsenic, cadmium, mercury). Top-shelf brands test every batch. Waxx publishes pass on every batch.
07

Microbial

Pass or fail per microbial category (E. coli, salmonella, mycotoxins, total yeast and mold). Pass means the batch is clean of biological contamination.

FAQ

Quick answers.

How do I read a cannabis lab certificate?

A cannabis COA shows total cannabinoids percent, individual cannabinoid breakdown, terpene profile, and pass/fail on pesticides, residual solvents, heavy metals, and microbials. Pass on all four contaminant categories is required.

What is a good cannabinoid percentage?

Live Resin typically tests 80 to 90 percent total cannabinoids. Live Diamonds tests 85 to 94 percent. Higher is not always better. Flavor and terpenes also matter. Read the full panel, not just THC.

Where does Waxx publish lab results?

Every Waxx batch publishes its full lab certificate to waxxbrandz.com/lab-results and the verify page. Scan the QR on the package or look up the batch ID online.
