What is the Folate (Red Cell) Test?
If you’re experiencing anemia, your doctor will order a series of blood tests. The series of tests may include the red cell folate test – most often if your red blood cells are larger than normal called macrocytic anemia. Anemia of all kinds can cause pale skin, extreme fatigue, dizziness or loss of balance. If your red cell folate test results are lower than normal, your folic acid levels need to be boosted.  Folic acid, also known as folate, is extremely important during pregnancy. Without proper amounts of folate in the blood, the risk of neural tube defects increases.
