Order Vitamin A Deficiency TestVitamin A is a fat-soluble nutrient required for normal vision, immune function, and cellular growth. When intake or absorption falls short, retinol stores can become depleted, and a blood test helps determine whether a deficiency is present.
About Vitamin A Deficiency Test in Spring
The Vitamin A Deficiency Test measures retinol in the blood to assess whether levels fall below the reference range.
Retinol is the primary circulating form of vitamin A. Because the liver stores this nutrient, serum concentrations may remain normal until reserves are significantly reduced, making laboratory evaluation useful when clinical signs or risk factors are present.
Deficiency can arise from inadequate dietary intake, fat malabsorption conditions, liver disease, or certain gastrointestinal disorders. Symptoms may include impaired night vision, dry eyes, and increased susceptibility to infections, though these findings are not specific to vitamin A alone.
Results are interpreted alongside a person's medical history, dietary patterns, and other laboratory findings. A low value supports the diagnosis of deficiency, while normal values generally indicate adequate retinol status. Turnaround time is typically one to three business days.
