Description
Compare sample matrix, source and method labels literally.
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.
Compare sample matrix, source and method labels literally.
When to use this tool
Use Biomonitoring Sample Matrix Source Match when checking the stated specimen record, timing or monitoring-support convention.
How to use the tool and how it works
- Enter matrix, expectedMatrix, source, expectedSource, method, expectedMethod. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read matrixMatches, sourceMatches, methodMatches. Inspect matrixMatches, sourceMatches, methodMatches before interpreting the associated values.
Compare sample matrix, source and method labels literally. Return three independent equality flags against their supplied expected labels.1

}Limitations and assumptions
- Matching strings do not authenticate a specimen, establish method compatibility or verify a measurement.
- 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.
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.
