Question for those who took the 3 hour

Were you told that when you fasted you couldn't even have any water??

I am supposed to start fasting all food and drink starting at 8pm. Tomorrow I take the drink at 8am and then they are going to draw my blood every half hour for the next 3 hours. So that turns out to be a total of 15 hours with no water. This sounds insane to me. Especially since when I took the 1 hour and fasted for only 8 hours, I was so dehydrated it took 20 minutes to get blood from me (I have the black and blues on my arms and hands to prove it).

I called my Dr. office to confirm that this is what they wanted, and the nurse spoke with him and he said nothing to drink at all. I called the lab and asked them and they said they usually don't tell patients that, but if my dr is telling me that, then it is his orders and I should follow them.

Anyone else??

I didn't have that told to me when I went for the 3-hour. That's all I drank for the evening before the test and that morning to take pills and whatnot.

Re: Question for those who took the 3 hour

Yep, for me it was no water after midnight. It really wasn't as awful as I thought it would be though!

Good luck


ETA: When I had my second hour blood drawn I asked the nurse if I could drink and she said no

no water after midnight for me and on top of the blood being taken every hour, they wanted a urine sample every hour too which wasnt easy with no liquids in ur body.

Oh dear. This is going to be awful.

Thanks girls for the input

Re: Question for those who took the 3 hour

they told me I can have water

Re: Question for those who took the 3 hour

My OB said no water but when I got to the lab they told I should have been drinking water and let me have some before the drink. After you start the drink you are not allowed to have anything.

Re: Question for those who took the 3 hour

They shouldn't be taking blood every half hour, are you sure that's what they said? It's should be every hour.

My doc didn't give me any instructions. I went by what I read on here...stopped drinking around 9pm the night before. I was thirsty during the test, especially because I wanted to get the orange flavor out of my mouth. You'll be fine...

I was allowed to drink water up until the first blood draw at 7am. My fast started at 7pm the night before.

I passed the 3 hour with no problem.

eta - they will draw your blood a total of 4 times. Once when you get there. Then you drink the drink (I had 5 minutes to drink it). Wait 1 hour, blood. Wait 1 hour, blood. Wait 1 hour, blood and go home.

They did 2 blood draws in each arm. Wasn't bad at all. The first hour after drinking the glucose was the hardest because it did make me a little nauseous.
