About Vitamin A Deficiency Test in Pasadena
The Vitamin A Deficiency Test is a blood test that evaluates retinol, the primary circulating form of vitamin A.
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 health, and normal growth and development.
Deficiency can occur when dietary intake is insufficient, when fat absorption is impaired, or when the body's storage and transport mechanisms are disrupted. Because vitamin A is stored in the liver, blood levels reflect the balance between intake, storage, and use.
This test is typically ordered when a clinician suspects inadequate vitamin A status based on symptoms, dietary history, or an underlying condition that affects nutrient absorption. Results are interpreted alongside the broader clinical picture.
