About Vitamin A Deficiency Test in Walnut
The Vitamin A Deficiency Test evaluates retinol concentration in the bloodstream to assess whether vitamin A stores are adequate.
Vitamin A, also known as retinol, is necessary for the formation of rhodopsin, a pigment in the retina that enables vision in low-light conditions. It also supports immune defense, skin integrity, and normal growth and development.
Because vitamin A is stored in the liver, blood levels may not reflect total body reserves until stores become significantly depleted. Testing is typically used when clinical signs or risk factors suggest a deficiency.
Results are interpreted alongside symptoms, dietary history, and other laboratory findings. Turnaround time for this test is generally one to three business days, and preparation follows the lab's instructions.
