- Report lookup
- Public lookup on the laboratory’s siteJanoshik reports carry a task number and an access key. Both appear on the certificate and are entered together on the laboratory’s own results page.A lookup answers for the sample the laboratory received: it confirms a report exists and what it says, not that the vial in your hand came from that lot. The lot number on the vial has to match.
