About Vitamin A Deficiency Test in Davis
Vitamin A deficiency can develop when dietary intake is insufficient or when the body has difficulty absorbing or storing the nutrient.
Vitamin A exists in several forms, with retinol being the primary circulating form measured in blood. It is essential for the formation of rhodopsin, a pigment in the retina that enables vision in low light. Beyond vision, vitamin A contributes to immune defense, skin health, and normal growth and development.
Deficiency may occur due to inadequate dietary intake of foods such as liver, eggs, dairy, and colorful fruits and vegetables. Conditions that impair fat absorption, including certain gastrointestinal disorders, can also reduce vitamin A levels. Symptoms of deficiency may include night blindness, dry eyes, and increased susceptibility to infections.
The Vitamin A Deficiency Test typically involves a simple blood draw, and results are generally available within a few business days. Preparation instructions should be followed as provided by the laboratory. This test is not a substitute for clinical evaluation, and results should be interpreted by a healthcare professional in the context of overall health.
