Clinical Utility

Detect folate deficiency; monitor therapy with folate. Folic acid is essential for the conversion of serine to glycine, catabolism of histidine, and synthesis of thymidylate, methionine, and purine. Deficiencies may be detected both in serum and red blood cells. Red blood cells are generally macrocytic except in combined deficiencies of both folate and iron, common in malnourished individuals.
