About Vitamin A Deficiency Test in Pullman
This panel provides a direct measurement of circulating vitamin A, most often as retinol, which is the primary transport form of the vitamin in blood.
Vitamin A is a fat-soluble nutrient obtained from animal sources as preformed retinol and from plant sources as provitamin A carotenoids. The body stores much of it in the liver, so blood levels reflect the balance between dietary intake, absorption, and hepatic release.
Retinol is essential for the formation of rhodopsin, a light-sensitive pigment in the retina that supports low-light vision. It also contributes to epithelial integrity, immune cell function, and normal growth and development.
A deficiency may arise from inadequate intake, fat malabsorption conditions, liver disease, or increased demand during certain life stages. The Vitamin A Deficiency Panel is typically ordered when clinical signs or risk factors suggest depleted stores, and results are interpreted alongside the broader clinical picture.
