This result was run by Janoshik and reported to us by the vendor. We didn't commission the test or handle the sample. For most vendors we publish the numbers but not the certificates themselves: the lab documents name the supplier, and our suppliers sell to us on the basis that we don't route customers around them. Where a vendor's certificates don't name them, or the vendor sells here under its own name, we usually link to the lab's own copy. Results whose certificate we can publish are in the COA library.

The code above is the vendor's batch code, printed on the kit's packaging (the vials carry no label). Each result covers the batch it names. Vendors ship thousands of kits and restock continuously, so there's no guarantee your order comes from a batch listed here.
