What it shows
Folate (vitamin B9) is needed for cell division and making blood.
Units and conversion
Base unit: nmol/L. Most common on Russian reports: ng/mL.
- 1 ng/mL = 2.266 nmol/L · 1 nmol/L = 0.4413 ng/mL
Typical ranges
Your laboratory’s range comes first — it is printed on the report next to the result. Below is one laboratory’s adult range with its method: a reference, not a rule.
| Who | Range, nmol/L |
|---|---|
| Adults | 7–39.7 |
Range source: Лаборатория Хеликс — Витамин B9 (фолиевая кислота)
Good to know
Laboratories use different units: ng/mL or nmol/L (as at Helix). Conversion: ng/mL × 2.266 = nmol/L.
Why it can be higher
Common reasons discussed with a doctor. This is not a diagnosis.
- Taking vitamins and medicines with folic acid
Why it can be lower
- Little folate in the diet: cooking destroys the vitamin
- Poor absorption in the gut
- Pregnancy and breastfeeding
- Haemodialysis
What to ask a doctor
- Should B12 be checked together with folate?
Whom to see
A GP or internist.
