About Vitamin A Deficiency Test in Spring
The Vitamin A Deficiency Test evaluates retinol levels in the bloodstream.
Vitamin A exists in several forms, with retinol being the primary circulating form measured in blood. The test quantifies retinol concentration to help identify insufficient levels.
Vitamin A is required for the formation of rhodopsin, a pigment in the retina that supports low-light vision. It also contributes to immune defense, epithelial tissue maintenance, and normal growth and development.
Deficiency can arise from inadequate dietary intake, fat malabsorption conditions, or certain liver disorders. Symptoms may include night blindness, dry eyes, and increased susceptibility to infections. Results are interpreted alongside clinical history and other laboratory findings.
