Order Vitamin A Deficiency TestVitamin A is a fat-soluble nutrient involved in vision, immune function, and cellular growth. A Vitamin A Deficiency Panel measures retinol in the blood to assess whether circulating levels fall below the reference range. Because both inadequate intake and certain malabsorption conditions can deplete stores, this panel is used when a deficiency is suspected rather than as a routine screen.
About Vitamin A Deficiency Test in Corvallis
The Vitamin A Deficiency Panel quantifies retinol, the primary circulating form of vitamin A, to help identify a deficiency.
Vitamin A encompasses a group of related compounds, including retinol, retinal, and retinoic acid. Retinol is the form most commonly measured in blood because it reflects the body's available supply. Retinol supports the formation of rhodopsin, a pigment in the retina that enables vision in low light, and it contributes to immune defense and epithelial tissue integrity.
Deficiency can arise from prolonged inadequate dietary intake, fat malabsorption disorders, liver disease, or conditions that interfere with the storage and transport of the vitamin. Early depletion may not produce obvious symptoms, which is why laboratory measurement is useful when risk factors are present. Results are interpreted against age- and laboratory-specific reference ranges.
A single measurement reflects circulating retinol at the time of collection and may be influenced by recent intake, inflammation, and other health factors. Clinicians typically interpret the result alongside medical history, dietary assessment, and other laboratory findings. Follow-up testing or additional evaluation may be recommended based on the initial result.
