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.
As far as a blood test determining triglyceride levels is concerned, for 12 to 14 hours before the test, only water (no coffee!) is permitted. Overnight fasting is essential for an accurate measurement of blood triglycerides! In addition, alcohol should not be consumed for the 24 hours just before the test. You are also not supposed to take any vitamin supplements 24 hours prior to your fasting blood work.
