What is a Vitamin A Test?

Vitamin A, also called Retinol, has several immune-related functions serving as the first line of defense. It plays a significant role in strengthening the immune system, maintaining healthy skin and other parts of the body like the nose, and helping vision in low light conditions.

Deficiency or absence of Vitamin A in the body could result in various health conditions, from mild symptoms like dry skin and eyes to more severe cases of night blindness in adults and delayed growth in children. Therefore, it is vital to take a Vitamin A test for individuals who are at higher risk of developing Vitamin A deficiencies.
