Looking a report up yourself

Every certificate prints a Search Code in the table at the top right, formed from a short client prefix and the accession number. Enter it in the lab’s own lookup and the report comes back from the laboratory, not from the vendor.

Open the Freedom Diagnostics Testing lookup

A laboratory lookup answers for the sample the laboratory received. It confirms that a report exists and what it says. It does not confirm that the vial in your hand came from that lot, which is why the lot number on the vial has to match the certificate.

Across these certificates the median gap between labelled and assayed mass is 9.6%. That figure describes what the laboratory reported about the samples it received; it is a property of those samples, not a rating of the laboratory.
