Description
Subtract blank from measured, then multiply by (sampleVolume + diluentVolume) / sampleVolume and additionalDilution.
Dilution changes the concentration or source-equivalent quantity associated with a sample. A dilution fraction is the retained proportion; its reciprocal is a correction factor.
Subtract blank from measured, then multiply by (sampleVolume + diluentVolume) / sampleVolume and additionalDilution.
When to use this tool
Use Renal Sample Concentration Dilution Term when you need a supplied dilution or source-equivalent calculation.
How to use the tool and how it works
- Enter measured, blank, sampleVolume, diluentVolume, additionalDilution. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read dilutionFactor, originalConcentration. Use the output convention below.
Subtract blank from measured, then multiply by (sampleVolume + diluentVolume) / sampleVolume and additionalDilution. Return that combined dilutionFactor too.1

| sampleVolume | Sample Volume | Required. Finite number; strictly above 0. |
| diluentVolume | Diluent Volume | Required. Finite number; minimum 0. |
| additionalDilution | Additional Dilution | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |

| dilutionFactor | Dilution Factor | Required. Finite number. |
| originalConcentration | Original Concentration | Required. Finite number. |

}Limitations and assumptions
- Assumes compatible concentration units and additive volumes; negative blank-corrected concentrations remain possible.
- 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
Trace every dilution stage and volume basis from the bench record, including recovery and blank assumptions where relevant.
