What to look for first
Start with the product name, batch number, test date, lab name, CBD amount, and delta-9 THC amount.
What contaminant screening means
Some COAs include screening for pesticides, heavy metals, residual solvents, microbes, or other quality concerns. Check which panels were actually tested.
When to keep comparing
If a product has no COA, a mismatched batch number, unreadable results, or vague testing language, compare other options before buying.

Is a COA the same as a label?
No. The label is brand-facing product information; the COA is lab-facing test information.
Can a COA be old?
Yes. Check the test date and whether it matches the current batch.
Does a COA make a product safe for everyone?
No. It is one transparency signal, not personal health advice.
