About Vitamin A Deficiency Test in Poway
This test evaluates circulating Vitamin A (retinol) to assess whether the body has adequate levels for normal physiological function.
Vitamin A encompasses a group of related compounds, including retinol, retinal, and retinoic acid, along with provitamin A carotenoids such as beta-carotene. In the blood, retinol is the primary form measured because it reflects the body's available supply under most conditions.
Retinol is essential for the formation of rhodopsin, a light-sensitive pigment in the retina that supports vision in low-light conditions. It also contributes to immune defense, cell differentiation, and the maintenance of epithelial tissues.
Deficiency can arise from inadequate dietary intake, fat malabsorption disorders, liver disease, or conditions that impair the storage and transport of vitamin A. A blood test helps clinicians determine whether retinol levels fall below the reference range and whether further evaluation is warranted.
