Check it yourself
MZ Biolabs does not publish a public lookup we have been able to find, so this certificate can be read but not independently re-pulled from the laboratory. The document above is the copy the vendor published. Where a laboratory does offer a lookup, we say so and link 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.
