What does -20 mean for folate?

A value of -20 for folate typically indicates a deficiency in folate levels in the body. Folate, also known as vitamin B9, is essential for DNA synthesis and repair, as well as for red blood cell formation. Low levels can lead to health issues such as anemia and can affect fetal development during pregnancy. It is important to address folate deficiency through dietary changes or supplementation as needed.
