About Vitamin A Deficiency Test in Appleton
Vitamin A is a fat-soluble nutrient that the body cannot synthesize in adequate amounts on its own, so it must come from diet or supplementation.
Retinol, the circulating form of vitamin A, is transported in the blood bound to retinol-binding protein. Measuring retinol provides a direct indication of circulating vitamin A and is the most common laboratory approach for assessing deficiency.
Vitamin A is essential for the formation of rhodopsin, a light-sensitive pigment in the retina that supports vision in low-light conditions. It also contributes to immune defenses, epithelial tissue integrity, and normal growth and development.
Deficiency can arise from inadequate dietary intake, fat malabsorption conditions, liver disorders, or increased physiological demand. Symptoms may include night blindness, dry eyes, and increased susceptibility to infections, though clinical signs alone cannot confirm status without laboratory testing.
