A vitamin A and carotene blood test measures the levels of vitamin A and carotenoids, such as beta-carotene, in the blood. Vitamin A is a nutrient that is important for maintaining healthy vision, skin, and mucous membranes. Carotenoids are pigments found in certain fruits and vegetables that can be converted into vitamin A in the body.
To perform the test, a healthcare provider will collect a blood sample from a vein in the arm and send it to a laboratory for analysis. The laboratory will measure the levels of vitamin A and carotenoids in the blood sample. The results of a vitamin A and carotene blood test can help a healthcare provider diagnose and monitor conditions related to vitamin A and carotenoid levels, such as vitamin A deficiency or excess, liver problems, and malnutrition.
