Discover your vitamin A levels with a vitamin A blood test.

Optimize your nutrition and overall well-being with our vitamin A blood test.

Vitamin A is a nutrient that’s vital for maintaining healthy vision, promoting healthy skin and supporting the immune system. It plays a role in cell growth, especially in the formation and maintenance of healthy teeth, bones, soft tissues and mucous membranes. Vitamin A is also important for reproductive health and maintenance of the heart, lungs, eyes and other organs.

Our trusted vitamin A test measures retinol, the active form of vitamin A in the body. A vitamin A deficiency may be due to inadequate vitamin A in your diet or a health condition that interferes with vitamin absorption. Symptoms may include dry eyes, difficulty seeing in low light settings at night, skin conditions, and a weakened immune system.  This test can also identify too much vitamin A in the body.
