Clinical significance

The measurement of total folate (TFOL) provides information on the folate status of the individual. Serum folate is an indicator of short-term status, while red blood cell (RBC) folate is an indicator of long-term status. Folate is a B-vitamin that is naturally present in many foods. Your body needs folate to make DNA and other genetic material. Your body also needs folate for your cells to divide. A form of folate, called folic acid, is used in fortified foods and most dietary supplements.

The reference range of the red blood cell (RBC) folate level also varies by age, as follows :

Adults: 140-628 ng/mL or 317-1422 nmol/L. Children: Over 160 ng/mL or over 362 nmol/L.
