A glucose screening test is a routine pregnancy test that checks for gestational diabetes. The test checks for higher-than-normal levels of glucose in your blood. If GD goes untreated, it can raise the risk of a number of problems including:
Macrosomia or a too-large baby.
Preeclampsia, or the sudden onset of high blood pressure.
Jaundice, breathing difficulties, or low blood sugar for your baby after birth.
Higher risk of type 2 diabetes for your baby later in life.
Stillbirth.
Glucose screenings are an easy and effective way to catch gestational diabetes and get the problem under control, usually with simple lifestyle changes.
