BEST ANSWER :If you have time to come up with bleach then you have time to drink water. If you have an hour or so before you urinate then drink water constantly urinate once then go take the test. I have a friend who gets up drinks a gallon of water and a pot of coffee. He urinates once then takes the test. He says the liquid bypasses his kidneys and flushes straight out. I am not sure about that part but it will dilute the urine and you will pee clear. I have done it myself.
