Description
Return observation coverage after excluding planned duration.
Biomonitoring records connect specimens, analytical methods, observation durations and exposure windows. Literal matches and coverage shares describe supplied records, while specimen stability, actual exposure and the suitability of a health interpretation require independent measurement and professional assessment.
Return observation coverage after excluding planned duration.
When to use this tool
Use Collection Duration Coverage Share when checking the stated specimen record, timing or monitoring-support convention.
How to use the tool and how it works
- Enter observedDuration, intendedDuration, excludedDuration. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read eligibleDuration, coverage. Use the output convention below.
Return observation coverage after excluding planned duration. Require excludedDuration >= 0, intendedDuration > excludedDuration and observedDuration in [0,intended-excluded]; coverage = observed/(intended-excluded).1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| observedDuration | Observed Duration | Required. Finite number; minimum 0. |
| intendedDuration | Intended Duration | Required. Finite number. |
| excludedDuration | Excluded Duration | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| eligibleDuration | Eligible Duration | Required. Finite number. |
| coverage | Coverage | Required. Finite number. |

}Limitations and assumptions
- The exclusion rule must fit the observation protocol; this does not validate sample quality or infer exposure.
- 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
Inspect verified collection and laboratory records and use an appropriate exposure/measurement analysis; seek qualified professional interpretation for health-related decisions.
