Glucose (fasting): units, conversion and tracking
Updated
Short answer
Glucose (fasting) is reported in mg/dL and mmol/L. 1 mmol/L = 18.02 mg/dL.

What is glucose (fasting)?
Blood glucose, usually measured after an overnight fast.
BiomarkerHQ groups glucose (fasting) under Metabolic. On lab reports it can also appear as glucose, fasting glucose, fasting blood glucose, fasting plasma glucose, fasting blood sugar and blood glucose.
Glucose (fasting) units and conversion
BiomarkerHQ stores each glucose (fasting) result in the unit printed on the report, and charts and compares results in mg/dL.
1 mmol/L = 18.02 mg/dL
1 mg/dL = 0.05551 mmol/L
| mmol/L | mg/dL |
|---|---|
| 4 mmol/L | 72.06 mg/dL |
| 5 mmol/L | 90.08 mg/dL |
| 6 mmol/L | 108.1 mg/dL |
| 7 mmol/L | 126.1 mg/dL |
| 8 mmol/L | 144.1 mg/dL |
| 9 mmol/L | 162.1 mg/dL |
| 10 mmol/L | 180.2 mg/dL |
| mg/dL | mmol/L |
|---|---|
| 70 mg/dL | 3.885 mmol/L |
| 80 mg/dL | 4.44 mmol/L |
| 90 mg/dL | 4.996 mmol/L |
| 100 mg/dL | 5.551 mmol/L |
| 110 mg/dL | 6.106 mmol/L |
| 120 mg/dL | 6.661 mmol/L |
| 130 mg/dL | 7.216 mmol/L |
For another value, use the lab unit converter. It converts units only and does not interpret a result.
Before comparing glucose (fasting) results
Tracking glucose (fasting) over time
In BiomarkerHQ, each glucose (fasting) result is saved with its collection date, its unit and the reference range printed on that report. The timeline charts the results across your draws against the range from each of your own reports, and any two draws can be compared side by side.
- Keep the unit printed on each report. Convert only to compare.
- Keep each report's own range with its result. See why ranges differ between labs.
- Compare the same lab and conditions where you can. See how to compare two blood tests.
Frequently asked questions
Which units do labs report glucose (fasting) in?
Glucose (fasting) is reported in mg/dL and mmol/L. BiomarkerHQ stores each result in the unit printed on the report and uses mg/dL for charts and comparisons.
How do I convert glucose (fasting) from mmol/L to mg/dL?
1 mmol/L = 18.02 mg/dL. For example, 7 mmol/L is 126.1 mg/dL.
How do I convert glucose (fasting) from mg/dL to mmol/L?
1 mg/dL = 0.05551 mmol/L. For example, 100 mg/dL is 5.551 mmol/L.
What should I check before comparing glucose (fasting) results?
Results from a non-fasting sample are not comparable with fasting results.
Does BiomarkerHQ interpret my glucose (fasting) result?
No. It compares a result only with the reference range printed on your own lab report, as below, within or above, and does not say what the result means. Talk to a qualified clinician about your results.
