Order Vitamin A Deficiency TestVitamin A is a fat-soluble nutrient that the body cannot manufacture on its own, so its status depends on dietary intake and efficient absorption. A Vitamin A Deficiency Screen measures retinol in the blood to help identify insufficient levels. This test is typically ordered when clinical signs or risk factors suggest that vitamin A stores may be low.
About Vitamin A Deficiency Test in Normal
The Vitamin A Deficiency Screen is a blood test that quantifies retinol, the primary circulating form of vitamin A.
Vitamin A supports vision, immune function, and cellular growth. Retinol binds to a carrier protein in the bloodstream, and its concentration reflects the amount of vitamin A available to tissues.
Deficiency can arise from inadequate dietary intake, fat malabsorption conditions, liver disorders, or increased physiological demand. Because symptoms may be subtle at first, laboratory measurement provides objective information about retinol status.
Results are interpreted alongside clinical findings and other laboratory data. A low retinol level does not by itself establish a diagnosis, and a result within the reference interval does not rule out every form of subclinical deficiency.
