Four steps
Find the code on the certificate
Each certificate prints a sample ID.
Open the laboratory's own lookup
Search the sample ID on the laboratory's verify-coa page. Type the address yourself rather than following a link from the seller, and make sure the page is on the laboratory's own domain.
Compare the result with the vendor's copy
A real sample ID appears in the list with the laboratory's PDF, which should match the vendor's copy. The product, lot, client name, test date, purity and quantity should all match; any difference in these is a material difference.
Run the control check
An invented sample ID has no match. Change one character of a real code and look it up again: a lookup that answers every code proves nothing.
