Patient discussion about tolerance test

Q. When will I have the Glucose Tolerance Test? I am pregnant and wanted to know when I need to have the Glucose Tolerance Test and what is the test like.

A. The test is given between week 24 and week 28 of the pregnancy. First you drink glucose, which is very sweet. You can mix it will water to help it go down easier. Then, after an hour you will have a blood test to check your glucose levels.

Q. What Do my Oral Glucose Tolerance Test Results Mean? I had an Oral Glucose Tolerance Test last week. I am 26 weeks pregnant. The results I got are 132 mg/dL. What does this mean?

A. If your blood glucose level was greater than 130 mg/dL, your provider will likely recommend you take another diabetes screening test that requires you to fast (not eat anything) before the test. During this second test, called the 100-gram oral glucose tolerance test, your blood glucose level will be tested four times during a three-hour period after drinking the cola-like drink. If two out of the four blood tests are abnormal, you are considered to have gestational diabetes.
