Glucose Challenge Test (GCT): Key Information

What is a Glucose Challenge Test (GCT)?

The Glucose Challenge Test is a preliminary screening test performed during pregnancy to assess the body's ability to process sugar. It helps identify women who may be at risk of gestational diabetes mellitus (GDM).

Why is the GCT Important?

1. Early Detection: Helps identify women at risk of gestational diabetes early in pregnancy.
2. Preventive Care: Early detection allows for timely interventions such as dietary changes or further testing to manage blood sugar levels.
3. Health of Mother and Baby: Effective management of GDM reduces the risk of complications for both the mother (e.g., preeclampsia, cesarean delivery) and the baby (e.g., macrosomia, neonatal hypoglycemia).

When is the GCT Performed?

• Timing: Typically performed between weeks 24 to 28 of pregnancy, though this can vary depending on healthcare provider guidelines.
• Risk Factors: Recommended for women with risk factors such as obesity, family history of diabetes, previous history of GDM, or advanced maternal age.
