I went to a LabCorp in June. The collector lead me to a room with a bathroom adjoining, locked my purse into the drawer, told me to go into the bathroom and fill the cup up to a certain line (about 1.5 oz) and not to flush the toilet. I walk into the bathroom and shut the door and locked it. Fan was running. I had practiced the QF and being so quiet.. not necessary. The toilet water was blue and the toilet back was duct taped. I poured my sample in the cup while I went in the toilet. Opened the door, he was back in the office... I set my sample on the tray (perfect temp) and he came up and sealed the same container and had me initial it. Then I signed some paperwork and I left. Happily working. Thanks QF.
