Final answer:
During the Oral Glucose Tolerance Test (OGTT), the patient is given a standardized glucose solution to consume and their blood glucose levels are monitored to assess their ability to tolerate glucose. This test is used to diagnose diabetes or gestational diabetes.
Step-by-step explanation:
During an Oral Glucose Tolerance Test (OGTT), the patient is given a standardized glucose solution to consume. This test is used to evaluate how the body processes glucose and is often used to diagnose diabetes or gestational diabetes. The patient is kept on a carbohydrate-rich diet for three days before the test and their blood glucose is measured in fasting condition before being given an oral dose of glucose solution. Blood glucose levels are then monitored at regular intervals to assess the individual's ability to tolerate glucose.
