About Vitamin A Deficiency Test in Edwardsville
Vitamin A Deficiency Testing measures retinol, the primary circulating form of vitamin A, to help identify insufficient levels.
Vitamin A supports the formation of rhodopsin, a pigment in the retina that enables vision in low light. It also contributes to immune defense, skin integrity, and normal growth and development.
Because the body stores vitamin A in the liver, blood levels may remain normal until reserves are substantially depleted. Testing is therefore interpreted alongside symptoms, dietary history, and other clinical findings.
Results are typically available within one to three business days. Preparation instructions should be followed as provided by the laboratory performing the collection.
