Not trying to star an argument but how do you know? Did you work for one of these companies? If you do or did I am curious and have a few more questions as far as to what they do regarding collection. Please don't tell me "one of my friends works at Joe Urine Inc!" The sediment doesn't affect the test because urine can have sediment to begin with and I have frozen urine before and used it later. Most of the time the sediment dissolves during the reheat but sometimes it remains.
