Clinical Significance
Folate and vitamin B12 are necessary for DNA synthesis, and consequently normal red blood cell maturation. Folate deficiency can lead to macrocytic (megaloblastic) anemia. Low folate intake, malabsorption as a result of gastrointestinal diseases, pregnancy and
the use of drugs such as phenytoin, oral contraceptives and excessive concentrations of alcohol are causes of folate
deficiency. Low serum folate concentrations are an early indication of folate depletion and precede depletion in the
tissues. 2 Adequate folate concentrations during pregnancy are also important in the prevention of neural tube defects
(NTD) in infants. Folate supplementation prior to conception and in the first weeks of pregnancy reduces the incidence of
NTD affected births
