# Vitamin B6, Plasma

> This test measures the level of vitamin B6 in the liquid part of your blood. It helps show whether your body has enough of this nutrient to support healthy nerves, skin, and red blood cells. Doctors often order this test to investigate symptoms like numbness, tingling, or unexplained anemia. While the results help rule out a deficiency or toxic excess, the test cannot determine the specific underlying cause of the imbalance by itself.
