I missed this thread by about a week. I had to take a urine test for my PM dr. last week. I was concerned that the levels of Oxycodone would show up higher than expected. I took 20mg of Oxy @ 10 hrs before providing the sample. I drank 3 glasses of water, and a couple of Mt. Dew's. I pee'd @25 times before providing the sample. I was so worried, that I bought a 4 panel home test, and tested myself less than 1 hour after providing the sample. I tested negitive on it. I called the manufacturer, and they said that the test would show positive for opiates with percocet and Oxycontin. I gave the sample on Wednesday last week. I saw the Dr. today, Monday, and they didnt say anything about it. I dont know if they got the results back, or if my levels were within expected range. I am still worried though. Since I flushed myself enough to pass the at home test, do you think I had low enough levels on their GC/MS test to be ok?
