Vitaquest assay fail is not Eagle Labs assay fail
Tally assay misses against lots assay-tested in one Vitaquest QC cut. That tally is fail %.
Pair: Assay-fail rate on Stock. Other CMO: Eagle assay-fail. Moisture sibling: moisture-fail.
What you type
Assay fails — Lots that missed Vitaquest active / marker assay limits in the cut.
Batches — Lots that ran assay testing in that same Vitaquest cut.
Fail % = assay misses ÷ lots assay-tested × 100. A fat fail % usually means supplier lot drift — re-check those lots; never invent a fail chip.
What not to do
Skip inventing fail %. Skip dumping Eagle or NutraScience assay logs into Vitaquest fields. Skip folding moisture misses into assay tallies. Skip averaging every SKU when one lot owns the miss.
Related: Stock, Eagle assay-fail, NutraScience assay-fail, moisture-fail.
Procedure
- Type assay fails and batches from the assay log.
- Read fail %.
- Re-check supplier lots when fail % is material.
Failure modes
- Inventing fail %.
- Dumping Eagle or NutraScience CSV into Vitaquest fields.
- Treating moisture fails as assay.

FAQ
- Is this Eagle Labs assay-fail rate?
- Eagle Labs keeps a separate QC book. [Assay-fail rate](/manuals/eagle-labs-assay-fail-rate) is theirs. This page tallies Vitaquest assay misses only.
- Is this Vitaquest moisture-fail rate?
- Sibling Vitaquest test. [Moisture-fail rate](/manuals/vitaquest-moisture-fail-rate) is LOD / moisture. This page is active / marker assay misses.
- What fail % should I invent?
- None. Tally assay misses and lots assay-tested from the same Vitaquest QC cut.
