Diagnosis of gestational diabetes mellitus: can we avoid the glucose challenge test?

Objective: To identify risk factors for gestational diabetes mellitus (GDM) in patients who had either a normal or abnormal glucose tolerance test (GTT) after failing the initial glucose challenge test (GCT). If identified, consideration can be given to circumvent the glucose challenge test for those at risk.

Data Sources: A chart review was performed on 557 patients with abnormal GCT, 278 had an abnormal GTT (cases), and 279 had normal GTT (controls).
