About Vitamin A Deficiency Test in Poway
Vitamin A deficiency can develop when dietary intake or absorption is inadequate, and it may affect multiple body systems.
Retinol, the circulating form of vitamin A, is essential for producing rhodopsin, a pigment in the retina that supports low-light vision. Low levels can also impair immune responses and the maintenance of epithelial tissues.
Deficiency may result from limited intake of foods such as liver, eggs, dairy, and colorful plant sources, or from conditions that interfere with fat absorption. Symptoms can include night blindness, dry eyes, and increased susceptibility to infections.
The blood test provides a direct measurement of retinol concentration. Results are interpreted alongside clinical signs, dietary history, and other laboratory findings to determine whether supplementation or further evaluation is needed.
