About Vitamin A Deficiency Test in Apache Junction
The Vitamin A Deficiency Panel is a blood test that quantifies retinol, the primary circulating form of vitamin A.
Retinol is transported in the bloodstream bound to a carrier protein, which allows its concentration to be measured reliably. Because vitamin A is stored in the liver, blood levels tend to reflect overall body status only when stores become depleted or excessive.
Vitamin A is essential for the formation of rhodopsin, a pigment in the retina that enables vision in low light. It also supports epithelial tissue integrity and immune cell function. Deficiency can develop from inadequate dietary intake, fat malabsorption conditions, or certain liver disorders.
Symptoms of deficiency may include night blindness, dry eyes, and increased susceptibility to infections. The panel is typically ordered when a clinician suspects inadequate intake or malabsorption, or when monitoring a condition known to affect vitamin A status.
