Lab Testing Burden at 99% analytical success rate: a worked example

What does the result look like when analytical success rate reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when GMP, QA, QC, validation, manufacturing, or operations teams need a quick planning estimate to plan QC lab capacity and identify whether release, stability, or in-process testing will constrain production.

The inputs for this scenario

  • QC analyst shifts available: 4 shifts (unchanged)
  • Tests per shift: 480 tests / shift (unchanged)
  • Analytical success rate: 99 % (raised for this scenario; the documented default is 90)
  • Review and release yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross capacity = QC analyst shifts available × Tests per shift) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 units for good output capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 units for gross lab test capacity.
  • At this operating point the engine returns 19.2 units for uptime loss.
  • At this operating point the engine returns 57.02 units for yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where analytical success rate sits at 90% and the headline result is 1,676 units, this scenario comes in 10% above the baseline at 1,844 units.
  • A figure at this level is achievable when analytical success rate is genuinely sustained, not just peaked for a shift. It assumes a steady tests-per-shift rate; complex or first-time methods run slower than routine assays, so use a realistic blended rate rather than a best-case one.

Results at a glance

  • Good output capacity: 1,844 units (headline result)
  • Gross lab test capacity: 1,920 units
  • Uptime loss: 19.2 units
  • Yield loss: 57.02 units
