Verify a report

Enter the report number printed on any IGML document to confirm its details against the laboratory registry. Verification is free and available to anyone.

Enter the number exactly as printed, including the prefix, e.g. IGML2600147PX

Same-day registry

Every report number enters this registry the day its report is issued. If a number is genuine, it resolves here.

Matched inscription

Card Report stones carry the report number on the girdle, visible under 10x magnification.

Document security

Issued reports print on numbered stock with watermark and microtext. Any alteration voids the report.

Mismatch protocol

A document that does not verify should not be relied upon. Contact the laboratory; we investigate every mismatch.
