Lot Release Sample Load at 23% aql pull, quarantine, lims, review, and retest allowance: a worked example

This worked example runs the lot release sample load numbers for a tougher week than the baseline: 23% aql pull, quarantine, lims, review, and retest allowance instead of the typical 32%. Estimate QC and QA time required to pull, inspect, test, document, and disposition lot-release samples for clinical consumables or diagnostic kits.

The inputs for this scenario

  • Lot-release and retained samples to process: 360 samples (held at the documented default)
  • Sample handling and test documentation rate: 1.1 samples / min (held at the documented default)
  • AQL pull, quarantine, LIMS, review, and retest allowance: 23 % (the input this scenario stresses; the baseline uses 32)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base lot release sample load time = lot-release samples and retained samples รท sample handling and test documentation rate.
  • Required lot release sample load time works out to 403 min at these inputs, and this is the headline figure for the scenario.
  • Base lot release sample load time works out to 327 min at these inputs.
  • AQL pull, quarantine movement, LIMS entry, review, and retest allowance applied works out to 23 % at these inputs.
  • Sample handling and test documentation rate works out to 1.1 pieces / min at these inputs.

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 6.82% below the baseline at 403 min.
  • Use it when sizing the QC release bench for a production run, scheduling lot disposition, or quoting lead time from line-off to shippable. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Required lot release sample load time: 403 min (headline result)
  • Base lot release sample load time: 327 min
  • AQL pull, quarantine movement, LIMS entry, review, and retest allowance applied: 23 %
  • Sample handling and test documentation rate: 1.1 pieces / min

Run it with your numbers

  • To rerun this with your own numbers, open the live Lot Release Sample Load calculator, set aql pull, quarantine, lims, review, and retest allowance to your actual value, and adjust the remaining inputs to match your operation.
