This test measures levels of Vitamin A in the blood. Vitamin A, also known as retinol, is an essential nutrient for healthy skin, healthy eyes and vision, bone growth, immune function, and embryonic development. The body cannot produce Vitamin A so it must come from the food a person eats. The deficiency of Vitamin A is rare in the United States but may occur in people who do not get enough meat, fruits, and vegetables in their diet. The most common symptom of Vitamin A deficiency is night blindness. The primary causes of deficiency are malnutrition and malabsorption disorders such as celiac disease, cystic fibrosis, and chronic pancreatitis. Vitamin A toxicity is typically due to the overuse of supplements but may also be caused by diets that include large amounts of foods such as liver which are high in Vitamin A. This test is typically ordered when a person has symptoms that are indicative of vitamin A deficiency such as night blindness, dry eyes, skin or hair, lesions on the skin, anemia, gray spots on the eye lining, and repeated infections. It may also be used to monitor people with conditions that cause vitamin deficiencies such as celiac disease and Crohn's disease. Testing may also be ordered to check for Vitamin A toxicity. Because the common symptoms of toxicity are similar to other conditions, this is usually done when a person has taken high levels of supplements or has a diet high in Vitamin A-rich foods.

Fasting for 12 hours required. Refrain from consuming alcohol 24 hours before the collection.
