About Vitamin A Deficiency Test in Kenner
This blood test evaluates Vitamin A levels for deficiencies.
Vitamin A (retinol) plays an important role in the formation of rhodopsin, a pigment in the retina that enables vision in low light. Beyond the eye, retinol supports immune defenses, epithelial tissue integrity, and normal growth and development.
Deficiency can develop when dietary intake is inadequate, when fat absorption is impaired by gastrointestinal or liver conditions, or when the body's storage and transport of retinol are disrupted. Because the body stores vitamin A in the liver, early depletion may not produce immediate symptoms.
The test reports a retinol concentration that a clinician interprets alongside diet, medical history, and other laboratory findings. Results outside the reference range do not by themselves establish a diagnosis, and follow-up testing or additional evaluation may be appropriate.
