Some physicians use the 3 hour glucose tolerance test, although many may order the test in a duration of between one to six hours; it is also known as an oral glucose tolerance test OGTT to differentiate it from the intravenous glucose tolerance test IGTT.
The three-hour test is becoming less common, but at one time was the gold standard of diabetes diagnosis. Patients who have been ordered to undergo a 3 hour glucose tolerance test must prepare for at least three days prior to the test.
During these three days, you must eat normal meals, paying special attention that you are eating normal portions of carbohydrates. As the day of the test draws closer, you must not eat anything, or fast, for eight to ten hours prior to the beginning of the test. For this reason, many OGTTs are scheduled in the morning.

Patients displaying diabetic symptoms will show a higher than normal peak in the same time frame as healthy individuals. However, the return to normal occurs much slower.

Patients displaying diabetic results will normally be required to undergo another OGTT. Pregnant mothers can expect slightly different values. Medline Plus: Glucose Tolerance Test. Page content.
