Order Vitamin A Deficiency TestVitamin A is a fat-soluble nutrient that the body cannot manufacture on its own, so circulating levels depend on diet and on how efficiently the gut absorbs and the liver stores it. A Vitamin A Deficiency Test measures retinol in the blood to determine whether concentrations fall below the range associated with adequate status. Because retinol participates in vision, immune function, and cellular growth, a deficiency can affect several systems before obvious symptoms appear.
About Vitamin A Deficiency Test in Berkeley
Retinol is the principal transport form of vitamin A in circulation and the analyte most laboratories measure when assessing status.
The test quantifies retinol bound to its carrier protein, retinol-binding protein, which the liver releases into the bloodstream. Results are interpreted against reference intervals that account for age and physiological state, since requirements differ across the lifespan.
Vitamin A supports the formation of rhodopsin, a pigment in the retina that enables vision in low light. It also contributes to the integrity of epithelial tissues and to the differentiation and function of immune cells, which is why deficiency can manifest in more than one organ system.
Deficiency typically arises from prolonged inadequate intake, fat malabsorption conditions, or liver disease that impairs storage and mobilization. A blood measurement helps distinguish low body stores from other causes of similar symptoms and guides whether further clinical evaluation is warranted.
