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.
Fasting before a blood test is typically required for fasting glucose, fasting lipid panel, fasting metabolic panel, fasting cholesterol, HDL or triglyceride tests. These tests look for cholesterol and glucose levels in your blood, and any food consumed before the test will provide an inaccurate reading. Your doctor may recommend a certain time period for fasting; however, the standard amount of time is about eight to 12 hours of no food before having blood drawn.
