Glucose Screening Test

K - October 6

I am going to be taking a glucose screening test at my next appointment. My doctor told me not to eat anything for 3 hours before drinking the orange stuff. I have heard that some people who eat at all that day have had false positives. Anyone had experience one way or the other? I don't drink the liquid until 2:45, so I would really like to have an early lunch, but I don't want to take any chances as I really don't want to have to do the 3 hour test.

There is no problem eating 3 hours before. If really want to be on the safe side, don't eat anything sugary or starchy. Stay away from breads, fruits, and pasta. Have a nice chicken salad or something. You will be fine :)

K, how many weeks are you? My doctor hasn't mentioned this test yet, and was just wondering when you get it done, and what it's for?

I'm supposed to take the test on 10/26 (I'll be exactly 28W then 25W2D today). My instructions did not say anything about not eating 3 hours before. I think I'll have an early lunch to be on the safe side and follow Bonnie's advice. I'm scheduled to drink at 3:30 a half an hour before my appointment. They are going to draw blood at 4:30.

If it's the regular 1 hour test, there is no fasting, but for the 3 hour test, you need to fast overnight (they will test you in the morning)

I have to take mine next week. They told me to eat all of the normal things and keep your eating schedule as usual.

Last saturday I had the one hour done at Quest Diagnostics and they told me not to eat or drink anything but water for 8 to 12 hours. Friday night I had ice cream. The next morning I took the test. When I went to my doctors app I failed the glucose. So yestarday I had to go take the three hour test. Lets just say my arms are sore and bruised. I've had three needles in the left arm and two in the right. They also told me 8 to 12 hours for the 3 hour test aswell.

I was a little I did a little research. It appears that there are different types of Glucose Tests for the 1 hour. -> Blood glucose may be measured on a fasting basis, randomly (anytime), post prandial (after a meal), and/or as part of another oral glucose tolerance test. I guess eating or not eating depends on the type of test they are administering. I'm checking with my doctor to make sure they are giving me the random test. It's measured differently. Be sure to find out which one you're getting. K -> I know you don't want to take the 3 hour test with a false positive, but I think it's also important not to get a False Negative. Hope this helps.
