The most definitive test for gestational diabetes is the 100 g, 3-hour glucose tolerance test. This test is used to diagnose gestational diabetes if a woman has an elevated fasting glucose level or if two or more of the other glucose values (1-hour, 2-hour, or 3-hour) are elevated above the normal range. Given the patient's history of large-for-gestational-age babies and stillbirth, it is important to diagnose and manage any potential gestational diabetes to reduce the risk of complications.
