About this test

The vitamin A test measures serum retinol, a fat-soluble vitamin vital for vision, immunity, skin health, and growth.

Normal vitamin A levels are about 20–60 µg/dL, varying by lab.

Low vitamin A is common in malnutrition, fat malabsorption, celiac disease, and liver disorders. Vitamin A deficiency symptoms include night blindness, dry eyes, Bitot's spots, dry skin, and frequent infections.

High vitamin A levels, usually from excess supplements, cause toxicity: headache, nausea, liver damage, and bone pain. Excess intake during pregnancy can cause birth defects.

Fasting for 8–12 hours is usually recommended before a vitamin A test, and you may drink water during this time. Avoid alcohol for 24 hours before the test. Inform your doctor about any vitamin A or multivitamin supplements, as you may be advised to stop them temporarily. Follow your lab's specific instructions.
