Because I had my anatomy scan scheduled for the same day, I drank my glucola on the way to the Dr's office, did the scan (which took about 45 min), then had my blood drawn afterwards.
When I failed my screening
, I had to go to the hospital and do the 3 hour glucose
test. For that one, I was told not to eat anything after midnight and get to the hospital as early as possible (so that I could get the blood draw done sooner and be able to eat! lol).
