About the test

The Vitamin B12 and Folate Test measures the level of the vitamin B12 and folate in your blood. Vitamin B12 and folate are essential nutrients that are necessary for producing and maintaining red and white blood cells, supporting the nervous system, and helping to create DNA, the basis of all cells.

Vitamin B12 and folate must be supplied by the diet or through supplementation because the body is not able to produce them. Vitamin B12 and folate deficiency (low levels of vitamin B12 or folate) may be due to limited dietary intake, poor absorption, advanced age, certain medical conditions, or some medications. Low levels of vitamin B12 and folate can lead to anemia, nervous system conditions, and a variety of health issues. This test can help determine whether you have a vitamin B12 or folate deficiency.
