Order Vitamin A Deficiency TestVitamin A is a fat-soluble nutrient that the body cannot manufacture on its own, so its status depends on diet, absorption, and storage. A Vitamin A Deficiency Test measures retinol in the blood to help identify whether levels have fallen below the range needed for normal physiological function.
About Vitamin A Deficiency Test in Orange
Vitamin A supports vision, immune defense, and cellular development, and retinol is the form most often measured in circulation.
Retinol circulates bound to a carrier protein, which means blood levels can stay relatively stable until body stores are significantly depleted. For this reason, a serum retinol result is interpreted alongside dietary history, symptoms, and other clinical findings rather than in isolation.
The test is typically ordered when there are signs of inadequate intake or malabsorption, such as night vision changes, dry eyes, or recurrent infections. Conditions that interfere with fat absorption, including certain gastrointestinal and liver disorders, can also reduce Vitamin A status.
Results are reported as a concentration of retinol in the blood and compared against the laboratory's reference interval. Values below that interval suggest deficiency, while very high values may indicate excessive intake or a release of stored retinol, and both directions warrant clinical review.
