Vitamin A Blood Test - More Information

The vitamin A test, also known as a vitamin A blood test, retinol blood test and a vitamin A lab test, checks the vitamin A blood level.

Vitamin A as a term represents a group of nutrients that are important for vision health, immunity and growth processes in the body. Sometimes known by its components (retinol, retinal, retinoic acid and beta-carotene), vitamin A can be found in different types of foods.

Low vitamin A levels, also known as vitamin A deficiencies, can occur from inadequate intake, poor absorption or external interference from chemicals. Symptoms of vitamin A deficiency include poor night vision and damage to structures of the eye in addition to weakening the immune system. Vitamin A deficiencies can be improved by taking vitamin A supplements. Vitamin A can also be toxic to the body at high levels. Excessive vitamin A, or vitamin A toxicity, can cause bone fractures and birth defects in pregnant women as well as vomiting, hair loss, stomach pain and dry skin. Vitamin A levels are typically higher in women who are taking oral contraceptives.

Getting a vitamin A lab test near you is a straightforward process at a Quest Diagnostics lab. After you order online, simply get your blood drawn and you will be able to download your electronic results when available.
