Description
Sum nonnegative aliquotVolumes, subtract that sum and deadVolume from positive parentVolume for retainedParent, and divide totalAliquots by parentVolume for aliquotShare.
A research diary or bench measurement uses a defined observation window, clock, unit, and reference level. Missing timing, incomplete collection, and unverified measurements affect how a result can be interpreted. Record arithmetic and signal terms describe supplied data without establishing clinical status.
Sum nonnegative aliquotVolumes, subtract that sum and deadVolume from positive parentVolume for retainedParent, and divide totalAliquots by parentVolume for aliquotShare.
When to use this tool
Use Urinary Lab Aliquot Parent Share when you need a research-record or bench calculation with already supplied measurements, units, and observation boundaries.
How to use the tool and how it works
- Enter parentVolume, aliquotVolumes, deadVolume. Keep parallel arrays aligned. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read totalAliquots, retainedParent, aliquotShare. Use the output convention below.
Sum nonnegative aliquotVolumes, subtract that sum and deadVolume from positive parentVolume for retainedParent, and divide totalAliquots by parentVolume for aliquotShare. Require all deductions together no greater than the parent volume.1

}Limitations and assumptions
- Volumes must share one unit and represent distinct withdrawals. This does not verify sample identity, sterility, assay suitability, or actual recoverable volume.
- The field tables state structural bounds; the mechanics also specify cross-field constraints. Malformed inputs and unsupported domains cause errors. A successful false flag, empty branch value, or zero placeholder has the meaning stated above and is distinct from an input error.
- 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. Signed zero is exported as zero.
Alternative or Complementary methods
Use an appropriately validated measurement and analysis method for clinical interpretation. Verify diary completeness, clock conventions, and measurement units before combining these terms into a research summary.
