1-Hour Sugar Response Test - Glucose Test, 1-Hour Post 75g Glucose

The blood plasma glucose level is measured exactly one hour after ingestion of a standard oral solution containing 75 grams of glucose, as part of the oral glucose tolerance test (OGTT 75g). This reading provides a critical data point on the glucose curve, representing the peak of the initial insulin response and the body's ability to begin processing the sugar load. It is primarily used in the diagnosis of gestational diabetes (as part of a single screening or diagnosis) and in the diagnosis of type 2 diabetes or prediabetes.
