3 hr glucose test

Brandy
I went yesterday for my 1 hr glucose test and it came back at 164 so now I have to go do the 3 hr test. Who has gone through this and what were your results of the 3 hr? I am not sure how the test is really performed...for instance how many times do they draw blood and do they do finger or arm....and how long did it take for them to get back the results to you.
