Order Vitamin A Deficiency TestVitamin A is a fat-soluble nutrient required for vision, immune function, and cellular growth. A Vitamin A Deficiency Panel measures retinol in the blood to determine whether the body's stores are adequate. Because both insufficient and excessive levels can cause harm, testing is typically ordered when clinical signs or specific risk factors are present.
About Vitamin A Deficiency Test in Ruskin
The Vitamin A Deficiency Panel evaluates retinol concentration in serum or plasma to assess nutritional status.
Retinol circulates in the blood bound to retinol-binding protein, which is synthesized in the liver. Serum retinol reflects liver reserves only when those reserves are substantially depleted, so a low result generally indicates a meaningful deficiency rather than a marginal shortfall.
Vitamin A is obtained from preformed sources such as liver, eggs, and dairy, and from provitamin A carotenoids in plants. Conditions that impair fat absorption, including certain gastrointestinal and pancreatic disorders, can reduce uptake. The test is therefore most informative when interpreted alongside dietary history, symptoms, and other laboratory findings.
Results are reported as a concentration, and reference ranges vary by laboratory. A value below the lower limit supports a diagnosis of deficiency, while values within range suggest adequate status. Because retinol is transported by a binding protein, concurrent protein-energy malnutrition or inflammation can lower measured levels independently of actual vitamin A stores.
