Retinol (Vitamin A)

A Retinol Test detects the amount of vitamin A in the blood. Vitamin A represents a number of related compounds; retinol, retinal, retinoic acid, and a vitamin A precursor beta (b)-carotene. Vitamin A is important for night vision, for fighting against infection (body immunity), and in regulating the genes to make sure they function properly.
