Check physician: Typically at least a 12-hour fast is required for cholesterol and triglyceride screenings. Vitamin levels and glucose tests usually only require an eight-hour fast. Following the guidelines is important to make sure your blood sample is not influenced by food or drink.Water is allowed even when fasting. Usually your regular dose of medication can be taken, although some medicines do affect test.
