Someone sends you a screenshot with a big number and a green check mark. It looks official. But what, exactly, passed?
A screenshot can leave out the sample name, the date, the laboratory, or the tests that were run. Without those details, you're being asked to trust the conclusion without seeing the report.

A certificate of analysis, often called a COA, records results from testing a sample. California's cannabis regulator, for example, describes testing for contaminants and checking cannabinoid and terpene labeling. That's an example of one state's system, not a promise that every product everywhere follows it.
Look for the sample identification and report date. Check which tests appear. A result for one substance doesn't answer a question about something the laboratory didn't test.
Keep the claims the same size as the evidence
A lab result also isn't a study of how a product affects your sleep, anxiety, or other health concerns. A measured cannabinoid level cannot answer those questions by itself.
If all you have is a cropped image, it's fine to leave the question unanswered. You don't owe a confident verdict to a screenshot. Keep the full report if you have it, and don't use a test result to dismiss symptoms or replace medical advice.
