Description
Clinical significance, indications and contraindications for performing the test.
Vitamin A (retinol, axerophthol) is involved in the formation of rhodopsin in the retina, acts as a bone growth factor, and is a cofactor in the synthesis of steroid hormones. Vitamin A deficiency can cause night blindness, dry skin, hair loss, and, in severe cases, corneal clouding. Vitamin A deficiency can be associated not only with insufficient intake but also with chronic lipid malabsorption syndrome, liver disease, intestinal parasites, and alcoholism. Long-term use of high doses of vitamin A can result in hypervitaminosis, first causing fatigue and later growth disruptions and bone fractures.
