Vitamin C (ascorbic acid) is one of the most important antioxidants. Blood levels of vitamin C are used to measure nutritional, immune, and cardiovascular status. Low values occur in scurvy, malabsorption syndromes, inflammatory bowel disease, alcoholism, pregnancy, hyperthyroidism, and kidney failure. Smokers have also been shown to have lower levels than non-smokers.
Fasting overnight is preferred, but not required for this test. Take all medications as prescribed. Refrain from taking vitamin C supplements or fruits 24 hours prior to sample collection.
