Gestational Diabetes Mellitus (GDM) Test in Mumbai

The American Diabetes Association (ADA) recommends a 2-step process to screen and diagnose gestational diabetes mellitus (GDM) during pregnancy. This test is important because GDM is a type of diabetes that develops during pregnancy and can affect both the mother and baby's health. By identifying GDM early, doctors can take steps to manage blood sugar levels and improve pregnancy outcomes. The 2-step process helps identify women at risk for GDM who may need further testing.

Step 1: 50g Glucose Challenge Test (GCT)

• This is a screening test done without considering your last meal time.
• You'll drink a sugary drink containing 50 grams of glucose.
• One hour later, a blood sample will be drawn to measure your blood sugar level.

Step 2: 100g Oral Glucose Tolerance Test (OGTT)

• This confirmatory test is only needed if your 1-hour blood sugar level in the GCT is higher than 140 mg/dL.
• You'll need to fast for at least 8 hours before the test.
• A blood sample will be drawn first to measure your fasting blood sugar level.
• Then, you'll drink a sugary drink containing 100 grams of glucose.
• Your blood sugar levels will be drawn again at 1, 2, and 3 hours after drinking the glucose solution.
