"We trusted the certificate" is not an answer.
Walk one lot end to end: the read, the four lanes, the decision your policy produced, and the record you hand someone.
Document diligence only, never a safety or FDA-approval claim.
Veritura does not test medicine, approve suppliers, recommend purchases, or make medical, legal, product-safety, or FDA-approval determinations. There is no paid or subjective placement: suppliers cannot pay for a better result or a better position, no listing fee, no subscription, and no pay-to-rank. Where results are ordered rather than filtered, the order is set by a published documentation-coverage grade, and that grade is never a recommendation, a preference, or a statement about any product.
A COA check or Passport records whether the documents are complete and consistent. It is not a safety, quality, efficacy, legality, or FDA-approval claim.
