Oral Glucose Tolerance Test
The oral glucose tolerance test (OGTT) measures the body's ability to use a type of sugar, called glucose, that is the body's main source of energy. An OGTT can be used to diagnose prediabetes and diabetes.

How is a glucose tolerance test performed?
The glucose tolerance test is performed after the patient has had nothing but water for 10 to 16 hours. The patient has his blood drawn for a a baseline blood glucose level.
The glucose tolerance test is typically a 2-hour test that involves measuring the fasting blood sugar, then drinking sugar water and measuring the blood sugar levels 1 and 2 hours afterwards.
