About Vitamin A Deficiency Test in Keystone
Vitamin A deficiency occurs when the body does not store or obtain enough retinol to meet its physiological needs.
Retinol is the primary circulating form of vitamin A and is transported in the blood bound to retinol-binding protein. Because of this relationship, low retinol levels can reflect either inadequate dietary intake or underlying conditions that impair absorption, storage, or transport.
The test is most often ordered when a person has symptoms consistent with deficiency, such as night blindness, dry eyes, or increased susceptibility to infections. It may also be used when there is known malabsorption, liver disease, or a diet lacking adequate sources of preformed vitamin A and provitamin A carotenoids.
Results are interpreted alongside clinical findings and other laboratory data. A low retinol value suggests deficiency but does not by itself identify the cause, so follow-up evaluation may be needed to determine whether the issue is dietary, gastrointestinal, hepatic, or related to another systemic condition.
