Description
Measure a sample's signed offset from a supplied baseline elapsed time.
Endocrine records distinguish specimen matrices, assay methods, unit bases, reference editions and sampling clocks. A printed significant-digit count differs from numerical rounding, while a fasting label is a reported state rather than verified preparation. Image axes and result labels organize supplied observations without deriving hormone physiology or clinical interpretation.
Measure a sample's signed offset from a supplied baseline elapsed time.
When to use this tool
Use Endocrine Test Baseline Time Reference when you already have baselineElapsedMinutes, sampleElapsedMinutes and need to measure a sample's signed offset from a supplied baseline elapsed time.
How to use the tool and how it works
- Enter baselineElapsedMinutes, sampleElapsedMinutes. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read signedGap. Use the output convention below.
Return sampleElapsedMinutes-baselineElapsedMinutes.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| baselineElapsedMinutes | Baseline Elapsed Minutes | Required. Finite number. |
| sampleElapsedMinutes | Sample Elapsed Minutes | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| signedGap | Signed Gap | Required. Finite number. |

}Limitations and assumptions
- Both inputs need the same time origin and unit. No physiological baseline, dynamic response, protocol or appropriate sample timing is established.
- 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
Reconcile the laboratory report, specimen and method information, reference source and collection timeline before comparing results. Use the complete appropriate assessment for a clinical question; one clock correction, diameter ratio or recorded status does not provide it.
