Serum Folate Test

Serum Folate Test


A folate home blood test measures the amount of folate in the blood. Folate is one of different B vitamins.

The body needs folate for normal growth and to make red blood cells (RBC), white blood cells (WBC), and platelets. Folate also is important for the normal development of a baby (fetus).


Vitamin B12 or folate deficiency anaemia

These tests check:

  • whether you have a lower level of haemoglobin (a substance that transports oxygen) than normal
  • whether your red blood cells are larger than normal
  • the level of vitamin B12 in your blood
  • the level of folate in your blood

But some people can have problems with their normal levels of these vitamins, or may have low levels despite having no symptoms.
