What is a carotene blood test for ? Indicators are normal

Carotene (Caroten). Carotene has 4 isomers , of which beta-carotene is provitamin A. In the body, carotene is converted into vitamin A in the small intestine and in the liver. It is less absorbed than retinol. A lot of carotene is found in carrots, apricots and peaches. The normal serum carotene content is 48-200 mg / dL. Vitamin A is essential for the proper functioning of many body systems. With a deficiency of vitamin A, bone growth is disturbed, various skin disorders (hyperkeratosis ) appear , eye disorders: (night blindness, keratomalacia , xerophthalmia ) , infertility develops, immunity is impaired: the body's resistance to infection decreases. With an increase in the level of retinol (a form of vitamin A) in serum above 50 mg / dL, one speaks of an increased content of vitamin A in the body - hypervitaminosis, in which serious disorders in the body can occur. An increase in blood carotene content does not cause symptoms of hypervitaminosis A. Hypercarotinemia is manifested only by intense staining of the skin, especially the palms and soles, in a characteristic yellow color. The sclera, unlike jaundice, are not stained. We happened to see patients who, on someone's advice, in order to "strengthen their health", drank carrot juice every day for a long time and acquired persistent carotene staining of the skin. The final conclusion about the harmlessness of hypercarotenemia cannot yet be considered made.
