Lot Release Sample Load at 37% aql pull, quarantine, lims, review, and retest allowance: a worked example

What does the result look like when aql pull, quarantine, lims, review, and retest allowance reaches 37%? The full calculation is worked below with real intermediate numbers. a diagnostics or lab consumables team needs to staff release testing, reserve cleanroom or lab time, and predict whether lot release will delay shipment for a finished lot release

The inputs for this scenario

  • Lot-release and retained samples to process: 360 samples (unchanged)
  • Sample handling and test documentation rate: 1.1 samples / min (unchanged)
  • AQL pull, quarantine, LIMS, review, and retest allowance: 37 % (raised for this scenario; the documented default is 32)

Working through the calculation

  • Applying the documented formula (Base lot release sample load time = lot-release samples and retained samples รท sample handling and test documentation rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 448 min for required lot release sample load time, the number this scenario is built around.
  • At this operating point the engine returns 327 min for base lot release sample load time.
  • At this operating point the engine returns 37 % for aql pull, quarantine movement, lims entry, review, and retest allowance applied.
  • At this operating point the engine returns 1.1 pieces / min for sample handling and test documentation rate.

How this compares with the baseline

  • Against the tool's baseline example, where aql pull, quarantine, lims, review, and retest allowance sits at 32% and the headline result is 432 min, this scenario comes in 3.79% above the baseline at 448 min.
  • A figure at this level is achievable when aql pull, quarantine, lims, review, and retest allowance is genuinely sustained, not just peaked for a shift. It assumes a steady average handling rate, so it understates time when a lot triggers an out-of-specification investigation or a full retest cascade rather than routine documentation.

Results at a glance

  • Required lot release sample load time: 448 min (headline result)
  • Base lot release sample load time: 327 min
  • AQL pull, quarantine movement, LIMS entry, review, and retest allowance applied: 37 %
  • Sample handling and test documentation rate: 1.1 pieces / min
