because it shows how well your body breaks down sugars, so they don't want anything else interfering, if I understand it correctly. It's better to fast to get a "true reading." But I know some places don't make you fast. I never did the 1 hour test, only the 3 hour with both babies and I could have nothing after midnight, not even water.
I didn't fast but its good to if you don't just don't have a bunch of sweets because it can give u a false positive result and then u have to do a 3 hour one and that one will have u feeling really sick
you have to drink it in under 5 minutes! I had orange the first time and hated it, I don't like orange flavored anything though, except for oranges. 😂 second time I had fruit punch, I much preferred that one, I didn't feel sick or have a headache after that one, the orange drink made me feel super sick.
I had the lemon lime and it tasted flat 7 up with a whole lot of extra sugar. it made me gag so much because it was so sweet. the phlebotomist told me not to throw up or else I'd have to come back.
