About Vitamin A Deficiency Test in Pullman
Retinol is the primary transport form of vitamin A in circulation and the standard marker used to assess status.
Vitamin A supports vision, immune function, and cellular differentiation. Rhodopsin, a pigment in the retina, requires vitamin A for the visual cycle, which is why deficiency can affect night vision.
Because vitamin A is stored in the liver, blood retinol levels may remain normal until stores are substantially depleted. Results are therefore interpreted alongside symptoms, dietary history, and other clinical findings.
Factors such as fat malabsorption, liver disease, and certain dietary patterns can influence retinol concentrations. A single measurement provides a snapshot, and repeat testing or additional markers may be considered when results are borderline.
