What happens if I fail my first glucose test and throw up during the 3 hour test?

You'll be rescheduled to try it again typically. I'd try to get ahold of that lemonade stuff people have been talking about as an alternative to the glucola drink, I've heard it's easier to keep down.

retest

My test was only 2 hours so maybe they could do a shorter test another option would be blood monitoring daily this was offered to me if I didn’t want to do the full test.

Typically if you can’t do the 3 hr they have you do the finger poke blood test at home for a week multiple times a day.
