What does high folate (vitamin B9) mean?
Higher values may occur with supplementation or increased intake. What counts as high depends on the reference range printed on your lab report, because ranges differ between laboratories.
What does low folate (vitamin B9) mean?
Lower values may suggest reduced folate availability for blood cell production. What counts as low depends on the reference range printed on your lab report, because ranges differ between laboratories.
Folate (vitamin B9) units and conversion
Mediki shows folate (vitamin B9) in nmol/L. Labs may report it in other units; Mediki converts them automatically so results from different labs line up on one chart.
| Unit on your report | Convert to nmol/L | Convert back |
|---|---|---|
| pmol/L | 1 pmol/L = 0.001 nmol/L | 1 nmol/L = 1,000 pmol/L |
| ng/mL, µg/L | 1 ng/mL = 2.273 nmol/L | 1 nmol/L = 0.44 ng/mL |
| ng/dL, ng/100mL, ng% | 1 ng/dL = 0.02273 nmol/L | 1 nmol/L = 44 ng/dL |
| ng/L | 1 ng/L = 0.002273 nmol/L | 1 nmol/L = 440 ng/L |

Why track folate (vitamin B9) over time?
A single folate (vitamin B9) result is a snapshot. Comparing it with your earlier tests shows whether a value is stable, slowly drifting, or responding to a change in treatment or lifestyle, which is often more useful than one number on its own.
