The Vitamin B9 (Folic Acid / Folate) test is used to determine the amount of folate in the blood. Folate is an essential water-soluble vitamin that plays a key role in DNA synthesis, cell division, and the production of healthy red blood cells.
Deficiency of folate can lead to megaloblastic anemia, fatigue, weakness, and in pregnant women, an increased risk of neural tube defects in the developing fetus. It is commonly seen in individuals with poor dietary intake, alcoholism, malabsorption disorders, or increased nutritional requirements.
This test helps diagnose folate deficiency, evaluate anemia, and monitor patients receiving supplementation. It is also important in assessing overall nutritional status and supporting healthy pregnancy outcomes.
