Entamoeba histolytica versus dispar Cyst Size Cutoff Micron Classifier
Record cyst diameter and explicitly refuse the erroneous size-only histolytica/dispar classification premise.
Description
Record cyst diameter and explicitly refuse the erroneous size-only histolytica/dispar classification premise.
Some Entamoeba species overlap in cyst appearance and size. Recording a diameter alone therefore cannot supply a reliable species distinction.1
When to use this tool
Record cyst diameter and explicitly refuse the erroneous size-only histolytica/dispar classification premise.
- Prepare the supplied observedDiameterMicrometres fields for this operation.
- Compare the complete example with the representation used by your own input before carrying the result into another step.
How to use the tool and how it works
- Enter observedDiameterMicrometres. Use the exact text syntax, units and index conventions explained below.
- Run the tool. If input validation fails, correct the supplied fields before interpreting any result.
- Read result.recordedDiameterMicrometres, result.sizeOnlySpeciesResolution, result.reason. Interpret false, null and empty lists using the distinctions below; they can be valid outputs.
Require a positive observedDiameterMicrometres, echo it as recordedDiameterMicrometres, and always return sizeOnlySpeciesResolution indeterminate with the stored overlap explanation.2
| Input field | Meaning and representation | Accepted input |
|---|---|---|
| observedDiameterMicrometres | observed diameter micrometres. | Finite number; greater than zero |
| Output field | Interpretation |
|---|---|
| result | Object containing the named outputs below. |
| result.recordedDiameterMicrometres | The recorded diameter micrometres value under the stated formula or text convention. |
| result.sizeOnlySpeciesResolution | The size only species resolution value under the stated formula or text convention. |
| result.reason | The reason value under the stated formula or text convention. |

}Limitations and assumptions
- No size cutoff is applied despite the tool ID. The tool does not examine an image or distinguish E. histolytica from E. dispar using additional laboratory evidence.
- Every declared top-level field is required and unexpected fields are rejected. Numeric inputs must be finite; ordinary text fields are bounded to 8,192 UTF-16 code units, with tighter operation-specific limits where stated.
- Ordinary string lists have at most 128 entries of at most 128 code units each; numeric lists and matrices have separate bounded size checks. Nonfinite results and excessively large serialized outputs are rejected.
- Indexes are zero-based and spans have an exclusive end unless explicitly stated otherwise. A valid false, null or empty-list result is distinct from malformed input.
Alternative or Complementary methods
Combine recorded observations with a validated method, appropriate controls and the complete specimen context. Use original qualified references when reviewing species, stages or product information; a supplied-record match, sample ratio or historical flag is only the stated piece of evidence.
