Folic acid deficiency is common in pregnant women, alcoholics, in patients whose diets do not include raw fruits and vegetables, and in people with structural damage to the small intestine. The most reliable and direct method of diagnosing folate deficiency is the determination of folate levels in both erythrocytes and serum. Low folic acid levels, however, can also be the result of a primary vitamin B12 deficiency that decreases the ability of cells to take up folic acid.

Transport Temperature: Refrigerated
Send serum in an amber tube. If amber tube is not available, wrap tube in aluminum foil to protect from light.
Most useful when ordered with vitamin B12 and red cell folic acid; detect folate deficiency; monitor therapy with folate; evaluate megaloblastic and macrocytic anemia. In mild folate and vitamin B12 deficiencies, serum folate and serum vitamin B12 can be normal. Homocysteine and methylmalonic acid are more sensitive indicators of mild deficiencies of these vitamins
