Understanding the marker
Folate (vitamin B9) helps your body make new cells, including red blood cells.
Folate is assessed with vitamin B12, the blood count, diet and medicines. These help distinguish a low circulating level from a deficiency that needs treatment. B12 status must be considered before treating suspected folate-related anaemia.
What does high Folate (B9) mean?
A high folate result is assessed alongside your vitamin B12 level, other blood tests and any medicines or supplements you take. Your doctor uses this information to decide whether follow-up is needed.
What does low Folate (B9) mean?
Folate is assessed alongside vitamin B12, your blood count and any symptoms you have. These help your doctor understand what a low result means for you and whether follow-up is needed.
