Yes I recently did mine and when u get there they immediately make you drink it.& you can't leave the office at all. Keep in mind you will be fasting and that drink can make you ill. But for whatever reason don't puke or else the test will be for nothing & you'll have to retake it. Good luck! @jrusky
u have 2 go 2 the lab n u will b fasting which u cant have anything after a certin time n they draw ur blood first then they give u a drink that u have 2 finish within a few minetes n it is gross n then u wait for an hour after u drink the drink n they draw ur blood again
