What is a Vitamin A Level test?
Vitamin A Level blood test is used to help diagnose vitamin A deficiency in people with symptoms, such as night blindness, or in people with diseases that impair intestinal absorption of nutrients and who are at risk of vitamin A deficiency.
Who should get this test?
A vitamin A test may be ordered when a person has signs that suggest a vitamin A deficiency or has general malnutrition.
Decreased Vitamin A Levels may cause:
- Night blindness
- Dry eyes, skin, and hair
- Ulcers and damage to the cornea, the outermost layer of the front of the eye that covers the iris and pupil
- Skin thickening and lesions
- Grayish spots on eye lining (Bitot spots)
