Check it yourself
You do not have to trust this page, or the vendor. Freedom Diagnostics Testing publishes its own lookup, so the report can be pulled from the laboratory directly.
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 and compare what it returns against the figures above. If the two disagree, the laboratory is right and we want to hear about it.
A certificate describes the sample it names and nothing else. It is not a statement about any other lot, and it is not an endorsement of the vendor or of any use of the material.
