Short answer: Evaluate the laboratory, requested question, sample custody and issued report before relying on “third-party tested” as a claim.
What to establish
Define the decision first: identity, chromatographic purity, quantitative content or another attribute. Ask the proposed laboratory about relevant competence, method scope, reference material, sample quantity, turnaround estimate and reporting limitations. Accreditation should be checked for the applicable scope, not assumed from a logo.
What to verify
In First1BioLab’s commissioned pre-purchase route, the buyer contacts the team; the manufacturer sends the proposed purchase sample to First1BioLab; the team documents receipt and coordinates submission to an independent laboratory. Confirm cost, shipping and custody details before dispatch.
Decision and next step
The laboratory issues its own report or COA if it uses that title. Compare its sample ID with transfer records and the supplier COA. The finding pertains to the tested sample; require a fresh link to a later bulk lot.
Practical request
Use the points above to request a defined product, sample or lot record. Ask the document issuer to explain any discrepancy; do not infer regulatory suitability from a catalog listing.
