How to use the Laboratory Unit Converter

Use the converter only after confirming the exact analyte and unit prefixes. A mathematically valid conversion can still be clinically wrong if the analyte, method, or specimen does not match.

Clinical boundary: These guides explain how to use the application. They do not replace the reporting laboratory, a validated diagnostic pathway, or patient-specific clinical judgment.

Safe conversion workflow

  1. Select the exact analyte-specific route.
  2. Confirm the source unit and destination unit.
  3. Enter the numeric result without thousands separators or unit text.
  4. Review the converted result and route-specific caution.
  5. Keep the original reported value in the clinical record.

Important exceptions

  • Enzyme activity conversions do not harmonize reference intervals across methods.
  • Lipoprotein(a) should not be converted with a fixed mass-to-molar factor.
  • HbA1c formula conversions are estimates and do not replace the reported result.
  • Qualitative, titer, index, and assay-specific results may not have a transferable conversion.

Rounding

Retain enough precision to avoid changing the interpretation, then round according to the destination laboratory or clinical convention. Do not manufacture precision beyond the source result.

Next step

Open the dedicated module and apply this workflow to the laboratory data while preserving the reporting laboratory's ranges, units, flags, and method context.
