Start with the purpose of the test
A potency measurement, a contaminant panel and consumer drug checking answer different questions. First identify the product, intended use and decision you need to make. Then ask a suitable laboratory which matrix, parameters and methods it can actually examine.
A report has limits
A cannabinoid profile does not establish the absence of pesticides, heavy metals or microbial contamination. Testing is neither a blanket safety guarantee nor a legal marketability decision. A fresh report for every batch is not promised unless confirmed and implemented as an operational rule.
Build your own reading checklist
Check batch identity, sampling, analysis date, tested parameters, units, reporting basis and limitations. Our guides cover reading reports, potential total THC, sampling, contaminant planning, laboratory selection and a practical request checklist. Regional pages distinguish official responsibilities from consumer services and commercial testing.
