About Vitamin A Deficiency Test in Peekskill
The Vitamin A Deficiency Test is a blood test that quantifies retinol, the primary circulating form of vitamin A.
Retinol is transported in the bloodstream bound to a carrier protein, and its concentration reflects the body's vitamin A status. Because vitamin A is stored in the liver, blood levels may remain normal until liver reserves become depleted, which is why testing is often interpreted alongside clinical signs and dietary history.
Vitamin A is required for the formation of rhodopsin, a pigment in the retina that supports low-light vision. Deficiency can impair night vision and, if prolonged, may contribute to dry eyes and other ocular changes. The vitamin also supports epithelial tissue integrity and immune cell function.
A deficiency may arise from inadequate dietary intake, fat malabsorption conditions, or certain liver disorders that affect storage and transport. Clinicians may order this test when symptoms or risk factors suggest insufficient vitamin A, and results are typically evaluated in the context of the individual's overall health.
