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.
Your levels of triglycerides (another type of fat in your blood) may also be affected by a recent meal. But you donât need to decide whether or not to fast; your doctor will tell you if you need to. If they say you should fast, theyâll likely suggest that you avoid eating for 9 to 12 hours before your test. For this reason, cholesterol tests are often scheduled in the morning. That way, you donât have to spend a whole day hungry while waiting to have your test.
