About Vitamin A Deficiency Test in Bothell
The Vitamin A Deficiency Panel quantifies retinol, the primary circulating form of vitamin A, to help identify insufficiency.
Retinol travels in the bloodstream bound to retinol-binding protein, which is synthesized in the liver. Because the liver stores substantial amounts of vitamin A, blood concentrations can remain stable until stores are significantly depleted.
Deficiency can arise from inadequate dietary intake, fat malabsorption conditions such as cystic fibrosis or celiac disease, and liver disorders that impair storage or transport. Symptoms may include impaired dark adaptation, dry eyes, and increased susceptibility to infection.
Results are interpreted alongside clinical findings and other laboratory data. A low retinol level supports a diagnosis of deficiency, while normal values generally indicate adequate status for the individual being evaluated.
