Pregnancy Weeks 25-28 – Glucose Test

There are several tests intended to identify gestational diabetes in pregnant women. These tests will diagnose whether diabetes exists or not by indicating whether or not the body is using glucose (a type of sugar) effectively.

One-Hour Glucose Test
-No special diet needs to be followed and you do not need to fast
-Drink glucola within 5 minutes
-Do NOT eat or drink anything after glucola (No mints, chewing gum, etc). Water is acceptable.
-Blood will be drawn one hour later.

All pregnant women should be screened for gestational diabetes (a condition that develops during pregnancy when the body is not able to make enough insulin).

If you test shows your blood sugar level was high, you will need another test:
