#1074 Usefulness of a Combination of a 48-Hour Fasting and a Glucagon Tolerance Test

Introduction: The 72-hour fasting test is the gold standard for the diagnosis of insulinoma. However, the test can become a burden for both patients and medical staff and, shortening the duration of fast has been attempted. There are several reports on the high sensitivity of fasting test but only a few reports on its specificity. An insulinoma can be localized using invasive tests such as endoscopic ultrasonography and selective arterial secretagogue injection test. Therefore, insulinoma detection with high specificity may be needed to avoid unnecessary examinations.
