About Vitamin A Deficiency Test in Poway
Vitamin A deficiency testing evaluates retinol concentrations in the blood to assess nutritional status.
Vitamin A, also known as retinol, is essential for the formation of rhodopsin, a pigment in the retina that supports vision in low light. It also contributes to immune function, cell growth, and the health of skin and mucous membranes.
Because vitamin A is stored in the liver, blood levels may remain normal even when liver reserves are depleted. A retinol measurement is therefore one part of a broader clinical picture that may include dietary history and other laboratory findings.
Deficiency can develop when intake is inadequate, when fat absorption is impaired, or when the body's demand increases. Testing provides objective information that clinicians can use to guide further evaluation and care.
