Item Catalog Number: LC004655
Vitamin B6 is a water-soluble vitamin that is widely available in fish, chicken, some fruits and vegetables, and wheat germ. It can be partially destroyed by overcooking.
Deficiency of this vitamin has been implicated in a wide variety of clinical conditions. B6 may be decreased with malabsorption and inflammatory disease of the small bowel, as well as alcoholism and diabetes mellitus.
Deficiencies may also impair red blood cell function and immune function. In adults, elevated serum homocysteine levels due to vitamin B6 deficiency may increase the risk for arterial plaque. B6 deficiency may also result in impaired amino acid metabolism.
Fasting is not required for this test. Always take your medications as prescribed. Do not take your supplements the morning of the blood draw.
