Lab result converter
Convert a blood test between US and international units. Pick the substance first: each has its own molar mass, so each converts differently.
That's about the same as a typical reading. Information only: read any result against your own laboratory’s reference range.
What it means
What is in there?
Information only, not medical advice. Reference ranges differ between laboratories, so always read a result against the range printed on the report.

Three things worth knowing
-
mmol/L = mg/dL × 10 ÷ molar mass
Creatinine of 1 mg/dL is 10 ÷ 113.12 = 0.088 mmol/L, or 88 µmol/L. The factor changes with every analyte.
-
Why molecules beat milligrams
Bodies react molecule to molecule. Counting in moles lets a doctor compare substances directly, which is why most countries switched.
-
One factor does not fit all
Using glucose’s factor on creatinine is out by 60%. Always check which substance a conversion table was written for.

Background
About lab units
US laboratories report by weight in mg/dL; most of the world counts molecules in mmol/L or µmol/L. Converting needs the molar mass, which differs for every substance: creatinine is 113.12 g/mol, urea 60.06.
