Reagent Fill Yield at 71% target reagent fill yield: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop target reagent fill yield to 71%, then walk the calculation through step by step. Calculate reagent fill yield for vials, bottles, assay cartridges, strips, or reservoirs based on fills that meet volume, dispense accuracy, and visual quality requirements.

The inputs for this scenario

  • Fills within volume and quality tolerance: 11,880 fills (held at the documented default)
  • Total reagent fills attempted or inspected: 12,000 fills (held at the documented default)
  • Target reagent fill yield: 71 % (the input this scenario stresses; the baseline uses 98.5)

Working through the calculation

  • The calculation starts from the formula this tool documents: Reagent fill yield = fills within volume and quality tolerance ÷ total reagent fills attempted or inspected × 100.
  • Reagent fill yield works out to 99 % at these inputs, and this is the headline figure for the scenario.
  • Gap to target yield works out to -28 points at these inputs.
  • Accepted reagent fills works out to 11,880 count at these inputs.
  • Total reagent fills works out to 12,000 count at these inputs.

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 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to target reagent fill yield, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. Yield alone doesn't tell you why fills failed — pair it with reject-category data (underfill, overfill, cosmetic, particulate) to drive root cause.

Results at a glance

  • Reagent fill yield: 99 % (headline result)
