I just switched OBs, and so, my glucose test is getting done tomorrow (late at almost 29w).
Anyway, it’s a 2hr fasting test, and she said if I threw up, it invalidated the results. Does anyone know if that means they start the two hours over that day, or if I have to start again a different day?
Last time, it wasn’t a fasting test, it was only an hour, but I’m really nervous about going for about 12 hours with no food.

I’m pretty sure it has to start on a different day since there would be no way to know how much of the glucose got into your system. Hopefully it won’t be that bad; I was on the verge of throwing up during the 4hr but that glucose drink is just so nasty… only the thought of having to come back again kept my gag-reflex in check! Maybe that’s why your doc told you, so there’d be an incentive to keeping it down!

Hi there, I work in a lab! When we have pregnant women vomit during this test, we usually reschedule it for a different day. Our procedure is to draw a fasting sample, then you drink the glucola (within about 5 minutes), then we draw another sample one hour from the time you finish the drink, then again in another hour, and sometimes again in another hour. So, if you were to get sick after drinking the glucola, our one/two/three hour samples will not accurately reflect how the sugar is metabolising in your body because, well, …it’s no longer in your body. Instead of starting the clock over again, we suggest rescheduling so you can rest, recover, and rehydrate for the day.
Make sure you eat a good meal tonight, focus on protein, and get as well hydrated as you can stand. Once you start the test, you can’t have any water either.
Bring a snack and a bottle of water with you so as soon as you’re finished you can grab a nibble.
Good luck 🙂

@DaneLady: Thanks, this is really helpful! What if I throw up before I drink the stuff, is that still okay? That’s what is most likely to happen, that while I’m getting dressed to go to the appointment, I’ll vomit.
@inspiredcreations: I know, when the nurse said it was a fasting test, I got all excited, and said “Oh, there’s no drink??” He just laughed and said “Oh, there’s a DRINK.”
On the plus side, the doctor said I had been doing so well with my weight gain, that at Christmas, if I wanted to eat a cookie, I could eat a cookie. Hell, she said eat two cookies.

@Quietserenity: I don’t think any throwing up BEFORE you drink the glucola is exclusionary, but make sure you hydrate, hydrate, hydrate. Your veins will be easier to work with if you aren’t terribly dehydrated.
