About Vitamin A Deficiency Test in Commack
The Vitamin A Deficiency Panel is a blood test that quantifies circulating retinol, the primary form of vitamin A in the bloodstream.
Vitamin A supports vision, immune function, and cellular growth. A deficiency can impair the production of rhodopsin, a pigment in the retina that is essential for low-light vision, and may also affect skin and immune health.
Retinol is carried in the blood bound to a transport protein, so levels tend to remain stable until body stores are significantly depleted. This makes the test useful for identifying pronounced deficiencies rather than marginal shortfalls.
Results are typically interpreted alongside clinical signs and dietary history. Because both deficiency and excess of vitamin A can be harmful, testing is generally ordered when a clinician suspects an imbalance rather than as a routine screen.
