About Vitamin A Deficiency Test in Queens
The Vitamin A Deficiency Test evaluates retinol concentrations in the blood to identify insufficient vitamin A status.
Vitamin A supports the formation of rhodopsin, a pigment in the retina that enables vision in low light. It also contributes to immune defense, epithelial tissue integrity, and normal growth and development.
Because vitamin A is stored in the liver, circulating retinol levels may remain stable until reserves become depleted. A blood measurement therefore reflects overall vitamin A status rather than recent dietary intake alone.
Deficiency can arise from inadequate dietary intake, fat malabsorption conditions, liver disorders, or increased physiological demand. Results are interpreted alongside clinical history and other laboratory findings.
