The Record

Every test Vector Analytical performs is issued to a numbered record. Anyone holding the certificate can check it here — no account, nothing to install.

What this check does and does not prove

A matching digest proves the document is byte-for-byte the one we issued. It does not prove the measurement was correct, and it does not prove the document describes the material you were sent — a genuine certificate can be attached to a lot it never described. That is why every record states the sample it covers.
