Description
Calculate allocated and unallocated blood-product split volumes.
Hematology records connect source annotations, specimens, instrument/reagent lots, unit bases and control references. A reported dilution correction depends on whether it has already been applied, while percentage and fraction are different representations. Local quantities and source tokens do not validate a sample, result or blood-product release.
Calculate allocated and unallocated blood-product split volumes.
When to use this tool
Use Blood Product Unit Split Balance when you already have parentVolume, childVolumes, documentedLoss and need to calculate allocated and unallocated blood-product split volumes.
How to use the tool and how it works
- Enter parentVolume, childVolumes, documentedLoss. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read unallocatedVolume, allocatedVolume. Use the output convention below.
Require parent/loss volumes>=0 and every child volume>=0; sum child volumes and return parent-allocated-loss.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| parentVolume | Parent Volume | Required. Finite number; minimum 0. |
| childVolumes | Child Volumes | Required. Array of finite number; maximum items 256. |
| documentedLoss | Documented Loss | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| unallocatedVolume | Parent-sum(children)-documentedLoss; signed balance, not release suitability. | Required. Finite number. |
| allocatedVolume | Allocated Volume | Required. Finite number. |

}Limitations and assumptions
- Negative residuals are retained and matching volume bases are assumed; no product identity, sterility, storage, release or safe transfusion is established.
- 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
Inspect the original laboratory, QC and product-traceability records before combining results. Use the complete controlled method and reporting convention; one target deviation, volume balance or censoring label does not establish quality or clinical interpretation.
