Description
Calculate a breath-sample time point from a supplied baseline and step interval.
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.
Calculate a breath-sample time point from a supplied baseline and step interval.
When to use this tool
Use Digestive Study Breath Sample Time Point when checking the stated gastrointestinal record, measurement label or timing convention.
How to use the tool and how it works
- Enter sampleIndex, suppliedMinutesPerStep, baselineMinute. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read sampleMinute. Use the output convention below.
Require whole sampleIndex>=0 and suppliedMinutesPerStep>0. Return baselineMinute+sampleIndex*step as sampleMinute.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| sampleIndex | Zero-based whole index; the positive step and baseline are caller-supplied study timing. | Required. Safe integer; minimum 0. |
| suppliedMinutesPerStep | Supplied Minutes Per Step | Required. Finite number; strictly above 0. |
| baselineMinute | Baseline Minute | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| sampleMinute | Sample Minute | Required. Finite number. |

}Limitations and assumptions
- A positive fixed step is a caller-supplied study schedule, not a recommended breath-test protocol or a verified collection event.
- 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.
