The glucose challenge test measures your body's response to sugar (glucose). The glucose challenge test is done during pregnancy to screen for gestational diabetes — a type of diabetes that develops only during pregnancy.

The glucose challenge test is done in two steps. First you drink a sugary solution. One hour later, your blood sugar level is measured. The results of the glucose challenge test indicate whether you might have gestational diabetes. If the test is positive, additional testing is needed to confirm the diagnosis.

The glucose challenge test is a modified version of the glucose tolerance test, a similar test used to screen for type 2 diabetes.
