About Vitamin A Deficiency Test in Campbell
Vitamin A deficiency testing evaluates retinol levels in the blood to assess whether the body has adequate stores of this essential nutrient.
Retinol binds to a carrier protein in the bloodstream, so a blood draw can reflect the amount of vitamin A available to tissues. Because levels can fluctuate with recent intake, inflammation, and other conditions, results are interpreted alongside a person's history and symptoms.
Vitamin A supports the formation of rhodopsin, a pigment in the retina that enables vision in low light. It also contributes to immune defense, skin and mucous membrane integrity, and normal growth and development.
Deficiency can occur when dietary intake is inadequate, fat absorption is impaired, or the liver does not store and release vitamin A properly. Testing is typically ordered when a clinician suspects deficiency based on symptoms, diet, or an underlying condition that affects absorption.
