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.
Other Considerations. Fasting for blood glucose tests may last as little as two hours, while most other tests need eight to 12 hours of dietary abstinence. Eat a balanced meal prior to your fasting period and again after your blood sample has been taken. Meet every criteria your doctor gives you, and if you make a mistake and take one of your supplements, let the laboratory technician know as soon as you arrive for your blood test.
