During an oral glucose tolerance test, a fasting blood sugar is obtained initially. The person is then asked to drink a sweet sugary beverage. Blood glucose levels are then obtained every 30 minutes for the next 2 hours. These individuals should be monitored and screened for diabetes in the future. This test is not diagnostic for diabetes, but if there is sugar in the urine, a blood glucose test should be performed.
Ketones are present in the urine when the body begins to breakdown fat for energy.
Ketones indicate that there is not enough insulin present to breakdown glucose. The presence of ketones can indicate a serious and potentially lethal complication of type 1 diabetes. This blood test is not used to diagnose diabetes, but rather to give information about how well a diabetic. It is a simple blood test that can be taken at any time. It will give your doctor important information that is needed to determine how much insulin you need to take or how your diet may need to be altered in order to keep your diabetes under the best possible control.
