Vitamin A, E, and Beta Carotene Blood Test Panel

A Vitamin A, E, and Beta Carotene Blood Test Panel is ordered to find out if you have excessive or deficient vitamin A, Beta Carotene, or Vitamin E levels in your blood.

The Vitamin A Test

Vitamin A is a group of substances that help in vision, reproduction, cell division, and bone growth. It also helps stem cells differentiate into different types of basic tissues.

Vitamin A helps to regulate the immune system, by making white blood cells that destroy harmful bacteria and viruses. Vitamin A may also help white blood cells fight infections more effectively.

The Beta Carotene Test

Beta Carotene is a substance that can be made into vitamin A in the body. It’s found in carrots, apricots, sweet potatoes, pumpkin, cantaloupe, winter squash, mangos, collard greens, spinach, kale, broccoli, and other oranges, red, and dark green fruits, and vegetables.

The Vitamin E Test

Vitamin E is a group of fat-soluble compounds that have certain antioxidant activities. Antioxidants protect cells from the damaging effects of free radicals. Free radicals damage cells and may contribute to the development of cancer and cardiovascular disease. Free radicals react rapidly with oxygen to form reactive oxygen species (ROS) that go on to damage cells. The body is also exposed to free radicals from air pollution, cigarette smoke, and ultraviolet radiation from the sun.

Vitamin E is a fat-soluble antioxidant that stops the production of ROS that is formed when fat is oxidized. Scientists are investigating whether vitamin E might aid in preventing or delaying the chronic diseases associated with free radicals.
