Lab key verifier
Janoshik reports carry a task number and a unique key. Janoshik's own verification page checks them. Enter both to build the link.
Both fields are printed on the report, usually near the top or beside the QR code.
When the result opens, compare
- The compound name, exactly as on your vial.
- The amount found against the label amount.
- The analysis date, which should be after the batch was made.
- The batch or sample description, against the batch on your vial.
- Every figure against the copy the seller sent you. Any difference means the copy was changed.
How this works
A certificate is evidence only when the laboratory that issued it will confirm it. Some labs publish a verification page where a task number and key, or a code, opens their own copy of the report. If the copy you were sent differs from the lab's copy in any figure, trust the lab's.
A report showing a task number, key and QR code; scanning or typing them opens the public record on tested.ph.
For Janoshik reports the tool builds the link to the lab's own verification page from the task number and key. For other labs it walks through the questions to ask when no verification route exists. For a full field-by-field read of a document, use the COA analyzer, and for the reasons behind each check see the lesson on verifying any COA in two minutes. Choosing between a lab abroad and a local test is covered in testing abroad or in the Philippines.
