Check it yourself
You do not have to trust this page, or the vendor. ILS Laboratories publishes its own lookup, so the report can be pulled from the laboratory directly.
Every ILS certificate carries a 7–8 character access code beneath the QR code in its header. Enter it on the laboratory’s verify page, or scan the code, and the report comes back from the laboratory’s own database.
Open the ILS Laboratories 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.
