Which test indicates GDM with a fasting level of 92 mg/dL or higher?

The 75 g Oral Glucose Tolerance Test (OGTT) is utilized to diagnose gestational diabetes mellitus (GDM) and sets specific thresholds that indicate a positive diagnosis. For this test, a fasting blood glucose level of 92 mg/dL or higher meets the criteria for GDM.

The 75 g OGTT is recommended by various professional organizations, such as the American Diabetes Association, as part of the diagnostic criteria for GDM, emphasizing the importance of monitoring fasting glucose levels alongside plasma glucose readings after the glucose load.

Other testing methods listed, such as the 1-Hour Glucose Load and the 2-Hour Glucose Load, serve different purposes or have different thresholds for diagnosis. The 100 g OGTT also assesses glucose tolerance but typically presents different criteria for diagnosing GDM, including higher thresholds for fasting and subsequent glucose levels.
