This blood test measures retinol, the primary circulating form of vitamin A, to help identify a deficiency when clinical signs or risk factors are present.
About Vitamin A Deficiency Test in Tamiami
Vitamin A supports vision, immune function, and cellular growth, and retinol is the form most often assessed in blood.
Retinol binds to a carrier protein called retinol-binding protein, which transports it from the liver to tissues. Because the liver stores most of the body's vitamin A, blood retinol can remain normal even when total body stores are low, so results are interpreted alongside clinical findings.
Deficiency can arise from inadequate dietary intake, fat malabsorption conditions, liver disease, or certain gastrointestinal surgeries. Symptoms may include night blindness, dry eyes, and increased susceptibility to infections, though these signs are not specific to vitamin A alone.
The test typically requires a blood sample, and results are reported as a concentration of retinol. Reference ranges vary by laboratory, and a low value is generally confirmed with repeat testing or additional markers before a diagnosis is made.
