A healthy result should fall into the range 18 - 77 ug/dL.

Vitamin A is one of the fat-soluble vitamins required for health. It’s especially important for vision, skin and mucous membranes found surrounding all organs. Vitamin A provides free radical-fighting functions for immunity and for anti-aging. It’s also critical for your thyroid to function properly. Studies in the last decade prove that vitamin A is important for gene expression regulation. This means that different diseases will be turned on if your genes are not “set” properly.

The Vitamin A test detects a deficiency of the vitamin. In children, a vitamin A deficiency will make them more susceptible to infections of all types, and their symptoms will become more severe. Also, the chance they will die from infections increases, with a death rate of more than 50%.

The vitamin A (retinol) test does not test for the Vitamin A plant sources called beta-carotene. Beta-carotene is a precursor of vitamin A, meaning they are converted to vitamin A by metabolism.

Normal Ranges for Vitamin A in mcg/dL: 

0-6 years: 11.3-64.7 mcg/dL

7-12 years: 12.8-81.2 mcg/dL

13-17 years: 14.4-97.7 mcg/dL

18 years and above: 32.5-78.0 mcg/dL

Critical Range: <20 mcg/dL indicates supplementation is needed. Levels <10 mcg/dL mean deficiency. Vitamin A levels>120.0 mcg/dL is suggestive of elevated levels and toxicity.
