What can I expect from the glucose tolerance test?

My mom told me they take blood.. And I want to know exactly how they are taking it. I hate needles and every time I have blood taken I either faint or feel extremely lightheaded. And I've also been told they'll prick my fingers. Now that I'm fine with.. I just don't want to get poked in the arm.. Please.. Which one is it.. My appointment for that is in a few days.

  • I never had to 'fast' or anything like that. I have it done 3 times and in a week I will go for a 4th time. I'm pregnant with my 4th. I go in an get blood, drink the juice, wait an hr and get blood drawn again. Thank goodness that my Ob is in his own practice and the only dr in the ofc. So I never had to go to a lab. I did my tests in his ofc. I failed once and had to wait three hrs, and was sent on my way... I actually liked the juice and it was a very pleasant experiance for me.

    I think the whole 'fasting' thing is what they used to do back in the day. Now I have freiends that say they were told not to eat or drink for about an hour before the visit, but I never had to do it.

  • If you are going to the lab (I work in one) what will happen is that you will be fasting (no food for 10-12 hours, generally overnight) they will take your blood (yes with a needle) and then you will drink a sugar drink(much like highly sweetened orange soda) and then have your blood drawn every hour on the hour for the designated amount of time that your doctor says (Between 1-3 hours generally).
    If you are doing it at your doctors office, they may be having you do the "Jelly bean" Method, in which you eat a designated amount of Orange Jelly Beans in 10 minutes, and then they take your blood sugar via finger stick.

  • For me they made me drink this really sweet orange drink. Then they drew blood out of my arm. It's not that bad, I promise. =) Don't stress over it. It will be done before you know it!

  • And the above poster is correct, you will need to have your pre-natal blood work done. But if you are at the stage for checking for Diabetes (I take it you are around 20-28 weeks?) Then you should already have had those done.

    Something else I forgot to mention, tell your Phlebotomist (the person who is going to draw your blood) that you are partial to fainting. They have special chairs for people who faint that they can put you in that is a lot safer than the regular ones that we use (This chair reclines back and therefore gets rid of the possibility of you falling onto the floor or anything silly like that. )

  • I used to be a phlebotomist. All the glucose tests I had done to me or did to patients were blood draws from the arm. Here's my best advice as a phlebotomist: 1. Tell them that you may faint. As a pp said, they have special chairs for that, or can even have you lie on a table (like the ones in an exam room). 2. Don't look when they stick you. Looking and waiting that way will tense you up and make it more likely that you will faint, and also possibly they won't get enough blood and have to do it again. 3. Tell them do not tell you when they are going to stick in the needle. We have a tendency to tell the patient when we are getting ready to put the needle in to prepare them. In your case, it would be better if you weren't prepared. Tell them to just stick the needle in. 4. Tell them you want an experienced phlebotomist, someone with at least a couple of yrs of experience. Good luck!

  • depends, are you having a 1,2, or 3 hour GTT (glucose tollerance test) I was given the 3 hour, and you drink glucola, which is basically the syrup they use for sodas, the lemon lime is the better of the flavors, they take your blood to see what your sugar level is, and then wait an hour, if you can take the test you drink the stuff, and then you wait and hour, then they take your blood then wait another hour, then take another blood sample, then wait another hour, then the last blood draw, take tums with you, cause you will get heartburn, but you cant take them during the test and no water either. also you have to have fasted for 12 hours priorto the test. I ended up with gestational diabetes.

  • after the initial shock of being with gest. diab. its not bad, they give you glyburide, and put you on a special diet, and then each week they increase your meds, if you can't get your sugars stabilized, you usually meet with a dietician that specializes in preg, and diabetes, then if that doesnt work, i was working out, but my sugars were still high, so then i went on insulin, and shooting myself, was no big deal, i actually prefered it, cause i could choose when and where. Then you go to the dr more often so they can monitor the baby more closely, and you get alot more ultrasounds, i had one every two weeks the last three months of my pregnancy
