Question

A 100g, 3-hour glucose tolerance test is the most definitive test in diagnosing gestational diabetes, especially for a patient with a history of large-for-gestational-age babies and a previous stillbirth. This test evaluates the body's ability to use glucose over a longer period of time and provides more accurate results than the other options. Choice A is an initial screening test that may require further testing if abnormal. Choice B checks only the fasting glucose level and may miss postprandial hyperglycemia. Choice C is an older, less common test that may not provide enough information for diagnosis.
