How should physicians interpret the new 2-hour oral glucose tolerance test in obstetric patients? Evidence-Based Answer: Screening at 24 to 28 weeks’ gestational age with a 2-hour oral glucose tolerance test (OGTT) is designed to identify patients with a 1.75 odds ratio of an adverse pregnancy related outcome compared with patients without gestational diabetes (GDM). While this test triples the number of patients identified as having GDM compared with screening with the 1-hour glucose tolerance test (SOR: B, case-control study and evidence-based guideline), it is not yet clear that this increased rate of diagnosis will improve maternal or fetal outcomes.
