Description
Measure a digestive test sample's signed collection-time offset.
Gastrointestinal study and procedure records use explicit specimen, assay, instrument, site and time conventions. A wet/dry mass label differs from converting a sample basis, while a recorded interval differs from a physiological transit estimate. Metadata alone does not establish anatomy, assay validity or a clinical finding.
Measure a digestive test sample's signed collection-time offset.
When to use this tool
Use Digestive Test Collection Time Offset when checking the stated gastrointestinal record, measurement label or timing convention.
How to use the tool and how it works
- Enter collectionTimestampSeconds, referenceTimestampSeconds. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read relativeSeconds. Use the output convention below.
Return collectionTimestampSeconds-referenceTimestampSeconds as signed relativeSeconds.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| collectionTimestampSeconds | Collection Timestamp Seconds | Required. Finite number. |
| referenceTimestampSeconds | Reference Timestamp Seconds | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| relativeSeconds | Relative Seconds | Required. Finite number. |
{
"input": {
"collectionTimestampSeconds": 750,
"referenceTimestampSeconds": 600
},
"output": {
"relativeSeconds": 150
}
}Limitations and assumptions
- No timestamps are parsed, clock offsets calibrated or clinical collection timing requirements selected.
- 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
Use original validated clinical/laboratory records and qualified medical interpretation for actual diagnostic, procedural or care decisions.
