The oral glucose challenge test is performed to screen for gestational diabetes.

When is the oral glucose challenge test performed?

Gestational diabetes is generally diagnosed between the 24th and 28th week of pregnancy. If you have had gestational diabetes in a previous pregnancy, or if your healthcare provider is concerned about your risk of developing gestational diabetes, the test might be performed earlier.
