It is not necessarily an advantage or disadvantage to fasting before labs. It depends on what test the doctor is asking for and what results are needed with the blood drawn.
If the doctor asks you to fast; he or she may be trying to determine your blood sugar levels while fasting or to see what your triglyceride and cholesterol levels are at the fasting time frame.
Fasting can and should make a difference that is why we ask; however, if a patient is diabetic, overweight, or in poor general health the labs may be affected no matter what they do.
