Certificate of analysis guide
What is a cannabinoid COA?
A certificate of analysis, or COA, is a lab report for a specific sample or batch. It can help show what was tested, what was found, and which questions the lab did not answer.
The short answer
A COA proves what was tested
A useful COA matches the batch in hand, names the lab and test date, reports cannabinoid amounts, and shows the contaminant panels that were run. It does not prove a health benefit.
Three checks
Start with identity, contents, and safety panels
Does the batch match?
The lot or batch number should match the item the report is supposed to describe.
What cannabinoids were measured?
Read the amount, unit, sample type, and whether the result refers to weight, volume, or serving.
What else was tested?
Pesticides, heavy metals, solvents, microbes, and mycotoxins are separate panels and may not all be present.
Public examples
Batch records must be specific
No public batch examples are listed yet. The reading guide is available now. A trustworthy example should identify the batch, lab, dates, tested panels, and source document without implying that lab quality proves a medical outcome.
