Reagent Fill Yield at 99% target reagent fill yield: a worked example

Push target reagent fill yield up to 99% and the picture changes. This example computes every intermediate figure at that operating point. a diagnostics or lab consumables team needs to track fill-line performance, investigate dispense drift, or estimate usable reagent-filled units for lot release for a reagent fill lot

The inputs for this scenario

  • Fills within volume and quality tolerance: 11,880 fills (unchanged)
  • Total reagent fills attempted or inspected: 12,000 fills (unchanged)
  • Target reagent fill yield: 99 % (raised for this scenario; the documented default is 98.5)

Working through the calculation

  • Applying the documented formula (Reagent fill yield = fills within volume and quality tolerance ÷ total reagent fills attempted or inspected × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 99 % for reagent fill yield, the number this scenario is built around.
  • At this operating point the engine returns 0 points for gap to target yield.
  • At this operating point the engine returns 11,880 count for accepted reagent fills.
  • At this operating point the engine returns 12,000 count for total reagent fills.

How this compares with the baseline

  • Against the tool's baseline example, where target reagent fill yield sits at 98.5% and the headline result is 99 %, this scenario lands almost exactly on the baseline at 99 %.
  • It divides good fills by total fills and multiplies by 100 to give a yield percentage, then subtracts your target to show the gap in percentage points. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Reagent fill yield: 99 % (headline result)
  • Gap to target yield: 0 points
  • Accepted reagent fills: 11,880 count
  • Total reagent fills: 12,000 count
