Blood cholesterol, triglyceride and glucose levels are the most common tests that require fasting. Vitamin levels, such as vitamin E or A, also need to be drawn when the patient is fasting. Typically at least a 12-hour fast is required for cholesterol and triglyceride screenings.
Sometimes this time frame is 6 to 8 hours and sometimes you might have to fast overnight. In some cases, you'll have to fast for up to 12 hours. Schedule your blood cholesterol test as early in the morning as possible if you're required to fast for 12 hours. You can stop eating at 6 p.m. or 7 p.m.
