Vitamin B12 and Folate

This tests for Vitamin B12 and Folate, which are vitamins that are necessary for normal red blood cell (RBC) formation, white blood cell (WBC) formation, repair of tissues and cells, and DNA production. Both must be supplied by the diet or supplementation because the body is not able to produce them.

People who are deficient in Vitamin B12 and Folate may not have any symptoms or may present with symptoms of anemia or nerve damage. General symptoms related to anemia and nerve damage include fatigue, weakness, difficulty concentrating, depression, numbness or tingling in the hands and feet, headaches, moodiness, and gastrointestinal symptoms. Some people may not have all or any of these symptoms but still have deficiency. Early detection is important to prevent irreversible damage over time, especially to the nervous system.
