Blood Tests
Read any result in 4 steps.
On every line, check four things: the result, the unit, the reference range and the flag. One out-of-range value alone is not a disease.
- Check the unit: mg/dL and mmol/L are different.
- Compare the result with the range on your own report.
- See whether you are near a limit or far from it.
- Compare with earlier results: direction says more than one value.
- CLSI C28-A3 — reference interval principles
