Description
Compute dry mass and divide blank-corrected signal times calibration by dry mass.
Specimen quantities can be reported on a volume, wet-mass or dry-mass basis. Conversion factors and usable-volume assumptions change the denominator; they do not validate the specimen or turn a numerical ratio into a clinical result.
Compute dry mass and divide blank-corrected signal times calibration by dry mass.
When to use this tool
Use Digestive Assay Mass Basis Factor when you need a specimen-volume or supplied mass-basis calculation.
How to use the tool and how it works
- Enter signal, blank, wetMass, dryFraction, suppliedCalibration. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read dryMass, amountPerDryMass. Use the output convention below.
Require positive wetMass and calibration and dryFraction in (0, 1]. Compute dry mass and divide blank-corrected signal times calibration by dry mass.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| signal | Signal | Required. Finite number. |
| blank | Blank | Required. Finite number. |
| wetMass | Wet Mass | Required. Finite number; strictly above 0. |
| dryFraction | Dry mass divided by wet mass in (0, 1], not a percentage. | Required. Finite number; maximum 1; strictly above 0. |
| suppliedCalibration | Supplied Calibration | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| dryMass | Dry Mass | Required. Finite number. |
| amountPerDryMass | Amount Per Dry Mass | Required. Finite number. |

}Limitations and assumptions
- Dry fraction is dry/wet mass, not percent. Negative corrected amounts are retained; units depend on calibration and no assay recovery or diagnosis is inferred.
- 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
Review the analytical preparation and source records for units, blanks, recovery and sample condition. Use a validated method and appropriate professional interpretation for health decisions.
