For screening and detecting moderate to severe vitamin B6 deficiencies.
This blood test is important as it evaluates vitamin B6 levels, which are involved in the process of making serotonin and norepinephrine. These two chemicals transmit signals in the brain. Vitamin B6 is also involved in myelin formation, a fatty protein layer that forms around nerve cells.
While mild vitamin B6 deficiencies are common, serious deficiencies can cause health problems in adults by affecting the skin, mucous membranes, nerves, and circulatory system. The central nervous system (CNS) can also be affected by vitamin B6 deficiency in children.
Testing should be done if you are at risk for a deficiency, have a condition that is associated with malabsorption, or when symptoms that may be due to a B6 vitamin deficiency are present.
This blood test usually requires fasting prior to sample collection.
