Order Vitamin A Deficiency TestVitamin A is a fat-soluble nutrient required for vision, immune function, and the maintenance of epithelial tissues. A deficiency can develop when intake, absorption, or storage of the vitamin is inadequate. This blood test measures retinol, the primary circulating form of vitamin A, to help identify a deficiency.
About Vitamin A Deficiency Test in San Jose
The Vitamin A Deficiency Test evaluates retinol levels in the blood to assess whether the body has sufficient stores of this essential nutrient.
Vitamin A, also known as retinol, is involved in the formation of rhodopsin, a pigment in the retina that supports low-light vision. It also contributes to immune defense and the health of skin and mucous membranes.
Because vitamin A is fat-soluble, its absorption depends on normal fat digestion and transport. Conditions that impair this process, along with inadequate dietary intake, can reduce circulating retinol and lead to deficiency over time.
Symptoms of deficiency may include night blindness, dry eyes, and increased susceptibility to infections. This test provides a direct measurement of retinol to help determine whether a deficiency is present.
