About Vitamin A Deficiency Test in Poway
Retinol is the primary circulating form of vitamin A and the standard marker used to evaluate status.
Vitamin A supports the formation of rhodopsin, a pigment in the retina that enables vision in low light. It also contributes to epithelial integrity, immune defense, and normal growth and development.
Because vitamin A is stored in the liver, blood retinol concentrations may remain normal early in deficiency and decline only when reserves become depleted. Results are therefore interpreted alongside clinical findings and dietary history.
Low retinol can reflect inadequate intake, fat malabsorption, liver disease, or increased demand. Elevated values may occur with excessive supplementation, which can be toxic. Reference ranges vary by laboratory, and a physician can explain what a specific result means.
