In short: laboratories in Europe mostly report in mmol/L and µmol/L, laboratories in the United States in mg/dL, and the two look nothing alike: a glucose of 5.5 mmol/L is 99 mg/dL. This converter switches between them for the common markers, in your browser, and explains what a reference range is. It does not tell you whether a value is normal for you; the range printed on your own report and your doctor do that.
Fifteen common markers
Glucose, cholesterol, triglycerides, creatinine, urea, uric acid, bilirubin, calcium, HbA1c, haemoglobin, ferritin, vitamin D and more.
Exact factors
The same conversion factors laboratories use, shown next to the result so you can check them.
Keep the series
Anpheros Daily reads your reports and converts units automatically, so results from any lab line up over the years.
How to use it
- Pick the marker.
- Type the value in the unit on your report.
- Read it in the other unit, with the factor used.
What a reference range is, and is not
The reference range on a lab report is the interval in which about 95% of healthy people's values fall, for that laboratory's method, and often for your age and sex. Five percent of healthy people are outside it by definition. A value just outside the range is a question for your doctor, not a diagnosis, and a value inside the range does not rule anything out either. Our guide on how to read lab results goes into detail.
Ranges differ between laboratories and methods, so this tool does not print one. Use the range on your own report.
Frequently asked questions
How do I convert glucose from mg/dL to mmol/L?
Divide by 18.016 (or multiply mmol/L by 18.016 to get mg/dL). 100 mg/dL is 5.55 mmol/L. The tool does this for you.
How do I convert cholesterol?
Total, HDL and LDL cholesterol: mg/dL divided by 38.67 gives mmol/L. 200 mg/dL is 5.17 mmol/L. Triglycerides use 88.57.
How is HbA1c converted from % to mmol/mol?
With the IFCC formula: mmol/mol = (% − 2.15) × 10.929. 6.5% is 48 mmol/mol.
Does the converter tell me if my result is normal?
No. It converts units and explains what a reference range is. Whether a value is normal for you depends on the laboratory's range, your age, sex and history, and that is your doctor's call.
Can I keep my results and see them over time?
Yes, in Anpheros Daily: photograph the report and the app reads the values and units, converts them automatically and lines up the same marker from different labs. See the lab results app.
