About Vitamin A Deficiency Test in Westminster
The test provides a direct measurement of circulating retinol, the primary form of vitamin A in the bloodstream.
Vitamin A exists in several forms, but retinol is the most reliable indicator of overall status. The liver stores the majority of the body's vitamin A, releasing it as needed to maintain steady blood concentrations. When dietary intake or absorption falls short, these reserves can become depleted.
A deficiency may arise from inadequate intake of animal sources or provitamin A carotenoids, fat malabsorption conditions, liver disorders, or increased needs during certain life stages. Because symptoms such as night blindness and dry eyes can appear gradually, laboratory testing offers an objective way to assess status.
Results are interpreted alongside clinical history and dietary patterns. Low retinol values suggest deficiency, while normal values generally indicate sufficient stores. Healthcare providers use this information to guide further evaluation and appropriate management.
