Glucose tolerance generally refers to the glucose tolerance test, and glucose tolerance test tests generally require a graduated cup. The glucose tolerance test is one of the most common ways to diagnose diabetes. The procedure of the glucose tolerance test is to drink a glass of 250-300 ml of sugar water containing 75 grams of glucose after drawing fasting blood, and then measure the blood glucose after 0.5 hours, 1 hour, 2 hours, and 3 hours, and make a judgment on the condition based on the blood glucose results. The glucose tolerance test should be performed under the supervision of a doctor to ensure patient safety and ensure accurate results. If the diagnosis of diabetes is confirmed, the patient needs to undergo standardized treatment under the guidance of a doctor to avoid delaying the condition.
