ALTERNATE

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.

A fasting specimen is preferred, ship on cold pack do not
freeze. Protection from light exposure (e.g., foil wrap) is not
required.

Both the HCT and folate will be performed on this tube. If sample
is sent frozen, a default hematocrit will be used for calculation
of the RBC folate. Do not freeze as this will affect the HCT.
