Yes, I just had my 24 wk appointment and scheduled my
glucose test for my next visit. My doctor also sent the drink home with me, with instructions on when to take it. They have to draw blood exactly 1 hour after you finish the drink. if you take it at the office you'll have to sit around and wait. If they send it with you, you won't have to stay as long and they can draw your blood as soon as you get there.
