What is folate?
A B vitamin needed to make DNA and red blood cells.
BiomarkerHQ groups folate under Vitamins and minerals. On lab reports it can also appear as folate serum, serum folate, folic acid, vitamin b9 and folate total.
Folate units and conversion
BiomarkerHQ stores each folate result in the unit printed on the report, and charts and compares results in ng/mL.
1 nmol/L = 0.4414 ng/mL
1 ng/mL = 2.266 nmol/L
| nmol/L | ng/mL |
|---|---|
| 5 nmol/L | 2.207 ng/mL |
| 10 nmol/L | 4.414 ng/mL |
| 15 nmol/L | 6.621 ng/mL |
| 20 nmol/L | 8.828 ng/mL |
| 30 nmol/L | 13.24 ng/mL |
| 40 nmol/L | 17.66 ng/mL |
| 50 nmol/L | 22.07 ng/mL |
| ng/mL | nmol/L |
|---|---|
| 2 ng/mL | 4.531 nmol/L |
| 4 ng/mL | 9.062 nmol/L |
| 6 ng/mL | 13.59 nmol/L |
| 8 ng/mL | 18.12 nmol/L |
| 10 ng/mL | 22.66 nmol/L |
| 15 ng/mL | 33.98 nmol/L |
| 20 ng/mL | 45.31 nmol/L |

Before comparing folate results
Tracking folate over time
In BiomarkerHQ, each folate 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 folate in?
Folate is reported in ng/mL and nmol/L. BiomarkerHQ stores each result in the unit printed on the report and uses ng/mL for charts and comparisons.
How do I convert folate from nmol/L to ng/mL?
1 nmol/L = 0.4414 ng/mL. For example, 20 nmol/L is 8.828 ng/mL.
How do I convert folate from ng/mL to nmol/L?
1 ng/mL = 2.266 nmol/L. For example, 8 ng/mL is 18.12 nmol/L.
What should I check before comparing folate results?
Serum folate and red-cell folate are different tests and are not interchangeable.
Does BiomarkerHQ interpret my folate 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.
