About Vitamin A Deficiency Test in Wheeling
This blood test is used to evaluate Vitamin A levels for deficiencies.
Vitamin A encompasses a group of related compounds, including retinol, retinal, and retinoic acid. Retinol circulates in the bloodstream bound to a carrier protein, which makes it measurable through a standard blood draw.
Retinol is essential for the formation of rhodopsin, a light-sensitive pigment in the retina that supports low-light vision. It also contributes to epithelial tissue integrity and immune cell activity, so a deficiency can affect multiple systems rather than the eyes alone.
Deficiency typically develops when dietary intake is inadequate, when fat absorption is impaired, or when the body's stores are depleted by illness. Because the liver holds substantial reserves, blood retinol may remain within range until those stores are significantly reduced.
