Check Your Folate Levels - Serum Folic Acid Test (Vitamin B9)

This test measures the concentration of folic acid (vitamin B9) in the liquid part of the blood (serum or plasma). This measurement reflects the level available to tissues at the time the sample is taken and is sensitive to short-term dietary changes. Folate is essential for DNA synthesis and cell division, particularly in the bone marrow that produces blood cells, and for the health of the nervous system.
