What are the recommended glucose levels for diagnosing gestational diabetes mellitus (GDM) according to the International Association of Diabetes and Pregnancy Study Groups (IADPSG)?
The IADPSG recommends diagnosing gestational diabetes mellitus (GDM) with a 75-g oral glucose tolerance test (OGTT) at 24–28 weeks' gestation. The diagnostic glucose levels are fasting blood glucose of 92 mg/dL or higher, 1-hour glucose of 180 mg/dL or higher, and 2-hour glucose of 153 mg/dL or higher.
The International Association of Diabetes and Pregnancy Study Groups (IADPSG) recommends a one-step method for diagnosing gestational diabetes mellitus (GDM). This involves administering a 75-g oral glucose tolerance test (OGTT) after an 8- to 12-hour fast. The test is conducted at 24–28 weeks' gestation. GDM is diagnosed if any of the following glucose levels are met or exceeded: fasting blood glucose of 92 mg/dL, 1-hour glucose of 180 mg/dL, or 2-hour glucose of 153 mg/dL. This method does not include a 50-g glucose challenge test (GCT).
Key points
- IADPSG recommends a one-step 75-g OGTT for GDM diagnosis.
- Testing occurs at 24–28 weeks' gestation after an 8- to 12-hour fast.
- Diagnostic criteria: fasting glucose ≥92 mg/dL, 1-hour ≥180 mg/dL, 2-hour ≥153 mg/dL.
- This method excludes a 50-g glucose challenge test.
