About This Test

Reason to Check It

"Folic acid (folate) is a B vitamin involved in many metabolic reactions in the body, including new cell growth. Maternal folic acid intake has been shown to reduce the risk of neural tube defects. Low levels of folic acid may be related to anemia, nutritional disorders, certain seizure prevention medications, excessive alcohol consumption,  metabolic disorders. Low serum folate may increase the risk of high blood pressure in women. Folate deficiency can cause poor growth, tongue inflammation, loss of appetite, diarrhea, irritability, or forgetfulness." - Dr. Alan Hopkins
