fentanyl urine test

Here is some surprising info. The urine test the Veterans Admin uses to "test people for the Fentanyl Patch use, does not test for the drug. It is a dummy test. They expect you to pop negative results for Opiods. Since Fentanyl is a synthetic derivative it will not test sensitive to the test. They would have to run a more expensive Immuno Assay test (Spelling?). They do the test to make sure you are not taking another prescription drug not prescribed by their doctors.....

It depends on the test that is being used and that the assay cutoff is for that particular test. The test for Fentanyl is specific to look for that drug and a normalized value can be detected usually 3-4 days after. You were given such a small dose IV, it may have been a much shorter time span.

The rpn said since I never failed a test she was going to have me do a saliva test. She also said that if fentanyl she’s up again she would not be able to give me my oxy. Ihave a appt with the dr next week. I am scared.

How close to a urine drug screen would I take my last 500 mcg. Fentanyl Troche for it to show up in my urine?? I happen to have a REALLY bad month & I want to make sure that it shows up positive...I can also explain to my doctor the horrible month I've have (some new pain & also some SERIOUS mental health issues with my son that I'm sure did nothing but make my already bad near daily migraines all the more worse...

They said it is extremely difficult to detect fentanyl in saliva and that these tests are not normally used for fentanyl patch users. They said urine tests are much more reliable and that I should have been given a urine test in their opinion. I also learned that I should have been told to wait at least ten minutes after eating or drinking, before taking the saliva test, because this can cause the results to be wrong.

t re-take the test, I think they should allow you to take the test again, let you put on a patch and then later do a urine test in front of them and see if the fentanyl shows up at that time. Instead these doctors that are testing patients and that are coming back with no fentanyl in their systems are just removing them from the practice and it just seems so cold.

Would ingesting or chewing a piece be enough to have a positive urine test? How quickly does Fentanyl show in the urine? My previous tests have not been a problem because I've had 'accepted level' of Fentanyl....though I don't know what that is. Previously I was on oxcodone for over 7 yrs and when I started abusing, I was switched to the patch and have not abused since.

I was telling her that effectiveness was failing after 48 hrs. She had do the urine test and it showed no narcotics in my system. I was wearing a patch that I had put on the previous morning, replacing the patch I had worn for 72 hrs. Any ideas or has anyone else had a similar experience?

I made a mistake with my calendar. I'm supposed to change patch every 3 days, but I forgot and didn't replace my patch until later on the 4th. I had my urine test sent in on that 4th day and I just realized what I did! It would be ok but I want to make sure the fentanyl test comes back positive from the lab. I've been a FAITHFUL pain management patient for almost two years and it would crush me if my doctor didn't trust me.

Tje last time I used was january 6th and I have been 100 percent clean since then. I had a random drug screen that is a urine test that gets sent to a lab so its pretty thorough and I tested positive for fentanyl 3 months after i used last. Is there any explanation for this.

I have a script for 10 mg vicodin but ran out and friend let ke take a 5mg oxy for my pain till script coupd be refilled...i then took a urine test..both meds re a class 2 schedule so will the urine test know the difference?

Apparently, the Fentanyl was not showing up in the office quick test. The office quick narcotic tests do not test for Fentanyl...my pharmascist told . In fact, I read on the internet that to get a test for Fentanyl, it is costly. I simply do not believe. I have bee "dope sick" having bad withdrawals for nearly two weeks because she cut me off cold...because I am under investigation. Today is Saturday...she works on Saturday as a drop in for her patients...

That way it will all be documented shoudl they decide to give you a urine test on that day - chances are, if they did, it would show that too much med is in your system, but that would be because of the ineraction between teh patch and the antibiotic. I know my post seems a bit involved and strange, but in basic words - using erythromycin - or an antibiotic in that same family - can greatly increase the amount of fentanyl found in your blood plasma.

I tried fentanyl patch but was very scared of the strength so stopped and wont go back there. How does talwin show on a urine drug test and how effective is it really. Also on tramadol er with my norco.

10 years ago I had the Roux-en Y Gastric Bypass surgery, which gave me malabsorption syndrome. That means that food, vitamins, minerals, meds, ect...do NOT digest in my "pouch", they digest in the lower intestine or go through my liver. So all meds had to be adjusted. I have had the same doctor for 3 years, she put me on Fentanyl 25 every 72 hours and 4 norco 5/325 for break through pain.

I'm on 125msg/h fentanyl patch, whats the recommended time for getting off the patch? my dr. is lowering it 25mcg/h every 20 days after being on the patch for 12 years. ALL BECAUSE MY URINE YESTS CAME BACK POSITIVE THIS YEAR AND THE LAST 4 YEARS TOO. BUT THEY DID NOTHING THE PREVIOUS 4 TEARS.

i am on the fentanyl 50 patch for ongoing hardware problems after a L4-S5 laminectomy with fusion in nov 2008. i also take Lortabs for occasional breaththrough pain. my doctor occasionally "drug tests" me but i am always too embarrassed to ask exactly what they test for. i dont do any illicit drugs and do not take any drugs not prescribed to me. my anxiety at this time is that i also have Klonopin prescribed to me by the same MD but only rarely take it.

went to urologist,gynecologist and nephrologist.all the tests like COMPLETE URINE EXAMINATION,URINE CULTURE,URINE FOR CHYLE AND 24HRS URINE EXAMINATION are normal.. ketones and albumines are not present in urine.. used FEMBIO capsules for 3 months and taking UTI OF tablets from 5 months as per doctor suggestion.problem intensity came down..but couldn't solve the problem completely.. please suggest me a solution and is there any other test to be taken to solve this problem Thank You.

I was on oxycodone 5mg and a fentanyl patch 12 mcg per hour my doc had me give a urine sample which i could have refused but thought I had nothing to hide. 2 weeks later I went in and he told me that my results were negative for both meds and my anxiety med that I take 1-3 times daily he said he had to discharge me. i begged him to give me another test and showed him that I had my patch on. they let me give another urine sample which again was negative.

The normal ratio should only have 3-4 x more norafentanyl to fentanyl. I also had no oxycodone in my system but did test positive for the metabolite in very small amounts. This prompted my doctor to consider testing me for genetic drug/enzyme metabolism. I still do not now the results of this, but since I have had the test done the test seems to have went from only taking 5-7 days to over 2 1/2 weeks.

I have passed every test for 3 years on my bi-monthly urine screen. All of a sudden I am showing positive for oxycontin and I have NEVER taken this med. Now I know that actiq,opana,stadol,and oxycontin are synthentic oipioids. Now I have taken a blood test for oxycontin only to make sure this is negative and a true false positive because I do not take this pain med. I am so upset because I have had to go through withdrawls and they are worse than the pain.

Im on oxycodone 60mg a day and fentanyl patches 75mg every 3 days. I swear on the bible i have never missed 1 dose. My pcp doctor drug tested me and claims NO drugs were in my system ! She claims i broke the drug contract i signed and wont see me anymore. How is this possible ? I demanded a retest and was told no, the dr even suggested my caregiver was taking them or we were selling the stuff !

I have an appointment with urologist on tuesday morning. He said he had never heard of fentanyl causing water retention and swelling. Have any of you experienced this? I will ask doctor to switch me to oxycontin 30 mg x2 day until they fix my neck on Feb. 24th. SANTA WAS VERY GOOD TO ME THIS YEAR. So incase I have all of you very confused, should I drink alot of water this week end? Thank you for reading this missive. I apoligize with the time line.

Most pain management programs have gotten strict, if the rx that is old was in your name you may be ok but its really up to the doctor, running out of meds in the programs here is just as bad as doing illegal drugs. Technically the Vicodin is a variance, its hard to say how your doctor would feel but mine requires me to take my rx & nothing else and have it in my urine when he asks me to take a test b/c with any variance you could loose your medicine. It all depends on your doctor.

What is causing the false positive for methadone? The urine test was done by an 11 panel urine tester. Can I ask for blood test? It ***** to be accused of something you have not done. The only difference in the last 2 years is that Lycra 50 mg 3x day and IB Profin every other day, I just started these 2 drugs in the last 4-5 weeks......that is the only difference.
