About Vitamin A Deficiency Test in Arcadia
The test provides a direct measurement of vitamin A status through a single blood draw.
Vitamin A exists in several forms, but retinol is the primary circulating form and the standard marker for assessing total body stores. The liver holds most of the body's vitamin A, releasing it into the bloodstream as needed, so serum retinol reflects whether that supply is adequate.
Deficiency can develop when dietary intake is insufficient, when fat absorption is impaired by gastrointestinal conditions, or when the liver's storage and release mechanisms are disrupted. Because vitamin A participates in rhodopsin formation in the retina and in the maintenance of epithelial tissues, low levels can affect night vision and increase susceptibility to infection.
Results are interpreted against established reference ranges, which may vary slightly by laboratory. A low retinol value generally prompts further evaluation to identify the underlying cause, while normal values indicate that circulating vitamin A is within expected limits. Clinicians use the result alongside symptoms, diet history, and other laboratory findings rather than in isolation.
