About Vitamin A Deficiency Test in Apex
The Vitamin A Deficiency Screen measures retinol in the blood to assess whether vitamin A stores are sufficient.
Vitamin A, also known as retinol, is essential for the formation of rhodopsin, a pigment in the retina that supports low-light vision. It also contributes to immune defense and the maintenance of epithelial tissues.
Because vitamin A is stored in the liver, blood retinol levels tend to remain stable until stores become significantly depleted. This makes laboratory testing useful for detecting a deficiency that may not yet produce obvious symptoms.
Results are typically available within one to three business days. Preparation instructions should be followed as provided by the laboratory performing the collection.
