Description
Descriptive fraction from caller-classified research counts; no cell identification, pathology grade or treatment implication.
Laboratory records distinguish specimen identity, sampling coverage, retained quantities, processing times, image scale, and measurement uncertainty. Areas, volumes, counts, and source-support flags measure different aspects of a record. A local calculation does not identify tissue or establish diagnostic adequacy.

When to use this tool
Use Tumor Research Cellularity Count Fraction when you need this specimen-record, sampling, processing-time, dimensional, or uncertainty calculation.
How to use the tool and how it works
- Enter designatedCells, otherCells, excludedCells. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read eligibleCells, fraction, excludedShare. Use the output convention below.
For nonnegative integer designatedCells, otherCells, and excludedCells require designated+other>0. Return eligibleCells=designated+other, fraction=designated/eligibleCells, and excludedShare=excluded/(eligibleCells+excluded).1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| designatedCells | Designated Cells | Required. Safe integer; minimum 0. |
| otherCells | Other Cells | Required. Safe integer; minimum 0. |
| excludedCells | Excluded Cells | Required. Safe integer; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| eligibleCells | Eligible Cells | Required. Safe integer. |
| fraction | Dimensionless fraction under the stated basis. | Required. Finite number. |
| excludedShare | Excluded Share | Required. Finite number. |

} Limitations and assumptions
- Cell categories are supplied and exclusions enter only the excluded-share base. This count fraction does not identify cells, assess specimen adequacy, diagnose a tumor, or select a clinical threshold.
- 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. Signed zero is exported as zero.
Alternative or Complementary methods
Use validated laboratory procedures, traceable measurements, and authenticated specimen records for a complete assessment. Check the relevant sampling and processing assumptions before interpreting a local quantity.
