I'd have to agree with Karen; my cousin works in the lab at a local hospital and they are constantly getting complaints about false positives for methadone, as well as percocet ( oxycodone with Tylenol ) not being in the patients system when prescribed. I know percocet has a short half life and one "friend" I know took a 10/650 percocet at 8:30am as witnessed by my sister and close to noon, had to take a drug test and absolutely nothing showed up in they're system, which resulted in this patient being discharged from they're practice and it was terrible. The only reason he didn't seek legal recourse, was he was afraid of his name being blacklisted by other doctors in the area and to see the suffering he went through because of being told he didn't take his medication and all but being accused of selling it ( he doesn't preach, but is a licensed minister with a lot of chronic pain issues ) really caused him and his family almost 2 years of suffering ( they had to all but do everything for him as he was all but bedridden with pain without the pain med's ).Thankfully, he found another doctor willing to treat him and he actually is able to go back to work some par time now. These drug tests, even according to my own cousin, are not absolute and most are not sensitive enough to prove you are taking your medications; most are designed to detect illegal drugs, or legal drugs not prescribed. She told me the threshold for percocet and most other pain medications are set too high to prove that the patient is "taking they're meds," as it is set to show zero if the level isn't above say "50 parts per million," and the patients actual reading is 49. Not being a lab tech, I may not have this exactly like she told me, but in summary, she told me the urine tests are the least accurate way of testing both legal and illegal substances. Its truly a shame so many innocent people are denied needed medications because of false positives for some drugs and negative readings when the person is taking they're medications, but it just doesn't show a high enough reading to score over the threshold limits. I really wish they're were enough people taking matters like this to an experienced attorney for legal recourse. I have so sympathy for someone abusing medications, dope heads or those just wanting a buzz at the expense of those of us in chronic pain needing medications, for to those of us in true pain, its rare we get any buzz off our medications--just some much needed relief from the hell we were unfortunate enough to get cursed with. My heart goes out to you and I pray your matter will be resolved and you can get the needed help you so desperately need. Inspectorgadget1956, Lumberton, NC

I Know for a fact that these drug tests can be inaccurate.Had md appt with PMD on 4/27/11..peed in a cup..nurse tested it..and came back in the room,and asked..WHY are you pos forbenzo??I said..Well seeing that the md has Valium Rx,that would be the benzo..hmmmm..and my tests were supposedly sent off for further testing...suggesting that I had hydrocodone in my UDS instead of Percocet.This is soo much untrue..A). I had no Rx for said med.2).Had taken my rx dose of Percocet at 9am,,appt at 10 am.So I get a call @ 7 pm on 5/18/11..stating that I was pos for that In my urine.I have called the Drug testing Corp..they said it takes 2 days for results..and Im informed on that day..when I had my appt on 4/27/11????Needles to say.I was fired from this Mds practice due to the inaccuracy of this all,left to fight my pain/withdrawals alone.

 DONT just take what is said by the docs staff as gospel..do some investigating of your own,to know errors are made.

Just wanted to let u guys know what happened with me...and Ill be the first to say that i am against diversion..but when im not guilty,Im against inaccurate tests as well.I have an atty too,btw.
