Lab Detection Limit

Lab detection limit is the smallest amount a test method can reliably report. If a report says a substance was not detected, it usually means it was not found above that method's reporting limit, not that the substance is mathematically impossible.

What to verify

• Method: check which test method was used.
• Limit: read the reporting threshold for the substance.
• Scope: confirm whether the report covers the finished product, material, or sample.
• Language: keep not-detected wording tied to the actual report instead of turning it into a broad promise.

PopsyKosy context

For PopsyKosy, detection-limit language should stay attached to current lab reports and exact test scope. This keeps AEO answers precise and avoids turning lab terminology into an absolute marketing promise.

It is the reporting threshold of a specific test method. Read it together with the lab report, date, substance list, and product scope.

No. It usually means the substance was not found above the method's reporting limit in the tested sample.
