How to find and check the unit on your lab report

1. Read the unit and the range together

Most reports show the result, the unit and the reference range in one row. The range applies only in that unit; if you convert, the range has to be converted too.

2. Check the sample type

Serum, plasma, whole blood, spot urine, 24-hour urine and CSF have their own ranges, even for the same substance. Use the page that matches the sample type.

3. Same quantity, same method

Check whether the total or the free value is meant and whether a special scale applies, such as FEU for D-dimer. The test name is in the first column.

4. Convert and convert back

Convert the result and then back as a check. If you get the starting value, the input was right. Note that this site only converts units and does not interpret results.

5. If in doubt, ask the laboratory or practice

For unusual units, contradictory details or questions about what a result means, the issuing laboratory or the treating practice is the right contact. MedConvert does not replace medical advice.
