Order Vitamin A Deficiency TestThe Vitamin A Deficiency Screen measures retinol in the blood to assess whether vitamin A stores are adequate.

This test offers a direct look at circulating levels rather than an indirect estimate.
About Vitamin A Deficiency Test in Burien
Vitamin A is a fat-soluble nutrient that the body cannot produce on its own, so its status depends on diet, absorption, and storage.
The test quantifies retinol, the primary circulating form of vitamin A, in a blood sample. Retinol travels bound to a carrier protein, and its concentration reflects the amount available to tissues. Because the liver stores most of the body's vitamin A, blood levels can remain normal until those reserves are substantially depleted, which is why results are interpreted alongside clinical context.
Vitamin A is central to the formation of rhodopsin, a pigment in the retina that enables vision in low light. It also supports epithelial tissue integrity, immune cell function, and normal growth and development. Deficiency can arise from inadequate intake, fat malabsorption conditions, liver disorders, or increased demand during certain physiologic states.
Results are typically reported as a numeric concentration and compared with the laboratory's reference interval. A low value may prompt further evaluation, while an elevated value can occur with excessive supplementation. Clinicians use the result together with symptoms, diet history, and other laboratory findings to determine what, if any, action is needed.
