Two Hour Glucose Tolerance Test

Dr. G had told me not to read lots of pregnancy information online, a policy I’m admittedly not good on at all. When Dr. G’s nurse had given me the information on the Glucose Tolerance Test to test for Gestational Diabetes,  I had been surprised as I had read a lot about it online, including that it was a one hour test, and if you failed that, there was a three hour test. So I was totally confused when the paperwork stated I would be taking a two hour test, a concept  had not considered at all.

Dr. G knew I’d been reading online again, and told me they just did the two hour now. I was given a list of places and times where it could be done. One lab had weekend hours, so I scheduled the test which required hours of fasting the test for a Sunday morning. Just like the DMV there was an appointment line and a non-appointment line.

Though I was there even before my 7 a.m. appointment time, the earliest they would accept an appointment, there was a woman ahead of me whose feet you can see above who also was there for a Glucose Tolerance Test.

The test starts with a blood test. Then you are given an extra sweet drink to drink. You have to drink it all in 5 minutes or less, or you automatically fail the test. The technician suggested drinking it fast so it would be easy to get it all down.

I decided to chug it relatively fast, sort of like I would have a large shot. I wish I had timed myself, my guess is it was about 30 seconds or less. The technician even gave me a wow so it must have been fast. I was told if I could not keep it down for the whole test that, too, was a fail, yet the label lists nausea and vomiting as possible side effects.

Then I had to wait, bring up paperwork to the desk (no waiting in line) 8 minutes before the time on the sheet for my second draw and repeat another hour later for three draws total.

In between I was told I could sit in the small waiting room (close to the desk) or the large one. When I was in the large one I was often all by myself.


I tried to not think about the sugary sweet mixture in my stomach and managed to keep it all down for the other two draws and beyond. Interestingly at no point did anyone ask if I had not done so, so I guess we were on the honor system.

I’ll be discussing the results of the test with Dr. G at my next appointment, tomorrow.
