Blood glucose levels are determined by a fasting blood sugar test. Prediabetes, diabetes, and gestational diabetes can all be diagnosed in this way, and it is quick, painless, and widely used. A healthcare provider may take blood by puncturing a vein in the arm or pricking the patient's finger. Before the exam, don't eat or drink anything (other than water) for at least 8 hours.
