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 in the liver. A Vitamin A Deficiency Test measures retinol in the blood to help determine whether levels are adequate. Because both too little and too much vitamin A can cause harm, testing is typically ordered when there is a clinical reason to suspect an imbalance.
About Vitamin A Deficiency Test in Wheaton
Retinol circulates in the blood bound to a carrier protein, and its concentration reflects the amount available to tissues.
Vitamin A supports vision, immune function, and cellular growth. In the eye, it is required to form rhodopsin, the pigment that allows the retina to respond to low light. When retinol stores fall, night vision and other functions can be affected.
Blood retinol is a relatively stable measure, but it does not always mirror liver reserves until those reserves are substantially depleted. Results are therefore interpreted alongside symptoms, dietary history, and other laboratory findings rather than in isolation.
Deficiency can arise from inadequate intake, fat malabsorption conditions, liver disease, or increased needs during certain life stages. The test is one part of a broader assessment and is not intended to diagnose a specific condition by itself.
