Citrate Tube Fill Reference Ratio Tool

Volume-ratio audit using supplied blood and citrate amounts; no specimen acceptance limit or clinical correction is inferred.

Description

Return collected/target, collected/citrate, and target/citrate ratios.

Laboratory labels and specimen ratios preserve supplied units, methods, and preparation quantities. A matching token or numeric ratio does not demonstrate calibration traceability or an acceptable clinical specimen.

Return collected/target, collected/citrate, and target/citrate ratios.

When to use this tool

Use Citrate Tube Fill Reference Ratio when you need one laboratory-record comparison under supplied conventions.

How to use the tool and how it works

  1. Enter collectedVolume, targetVolume, citrateVolume. Use the units and conventions below.
  2. Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
  3. Read fillFraction, bloodCitrateRatio, targetBloodCitrateRatio. Use the output convention below.

Require nonnegative collectedVolume and positive targetVolume and citrateVolume. Return collected/target, collected/citrate, and target/citrate ratios.1

Limitations and assumptions

  • CollectedVolume denotes the blood component on the same basis as targetVolume; ratios do not assess anticoagulant suitability, specimen acceptance, hematocrit adjustments, or coagulation validity.
  • Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
  • Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.

Alternative or Complementary methods

Use the full validated laboratory procedure and responsible professional review when determining specimen acceptance or clinical suitability.
