You will probably fail with all the worrying you are doing. Intense worrying has caused many to fail the day before your test. THC is released intensely into the bloodstream with the result being a failed test and your life ruined. Just kidding dude you will be fine. Just drink a couple of gatorades before your test piss 2 or 3 times and give midstream. Do not drink to much as you will produce a negative dilute. You will definately pass as those home tests are very accurate. Enjoy your new job.
