Pls Help False Positive For Methadone

Updated

I went to pain dr and tested positive for methadone. It's being sent to the lab. I did not take any methadone. Now I did take Xanax I was prescribed. I also take 30 mg Oxycodone. I went to the dr last week and the dr was not in the office. I got physically sick as I am new to all this back problem stuff. I take care of patients I am not normally the patient. My questions are this.. What does the lab do? What drugs illicit, prescribed and over the counter cause false positives. I promise this is not my expertise. I need to be fully aware. Do they release this info to my employer. What happens from here? If I know for a fact I didn't do what I'm being accused of, then why is it on my urine? I bought a 12 panel at cvs and it was negative on top of that. I'm so confused!

More precise testing from the lab will help show exactly what you took and eliminate false positives, that's why your doctor sent it on for more testing.

It is well known that opiates, such as Oxycodone, can cause false positives for their relatives on the less expensive, non-certified tests that most doctor's offices use. It happens anywhere from 4 to 50% of the time.

And no, your doctor cannot report it to your employer, that would violate current HIPAA laws.

You really need to relax and wait to see what the actual lab results show.

When will you hear back about them?

Possibly. Methadone has a half-life (on average) of about 24 hours. That means that, if you took 10 mg, 24 hours later you would still have 5 mg in your body. 36 hours after taking 10 mg you would still have 3.75 mg of methadone left. For some people (depending on their size) this will cause a positive result and for others it might not. I'd say "more than likely you will test positive", however. Good luck.

It will depend on the particular test they use, but you should deny it if you did not take it. Do not settle for that. Anytime there is a positive, the lab must verify it with a better test to pinpoint exactly what the problem is. If you are certain that you did not take methadone, there must be a false-positive meaning they could not have performed the confirmatory test which will find what chemical, metabolizes caused it. The lab has strict guidelines/procedures for this very thing. It is also possible the false-positive was caused by plain old human error. Again, only you know if you took methadone or not. If you did NOT, fight them and don't back down. They will either retest the sample they have or ask you to give another sample for test. There are many OTC meds that can cause false positives and you can find comprehensive lists if you google it. If Slick were you and there was a lot at stake, Slick would absolutely demand a new test and even get a lawyer if they won't work with you. Hope this was helpful for you, look me up I need advice too!

But methadone isn't chemically related to opiates or semi-synthetic opiates like oxycodone in any way (unless you count possessing a few of the same basic functional groups).

It's very possible. If you drink a lot of water now & the day of the drug test drink as much water as fast as you can you won't to pee 5 to 6 times and keep drinking water. Then when you take the test all you with pee is water because it will go through your body so fast it will be real clear. Trust me drink Enough water pee keep drinking water pee and more water when you have to pee Even 5 minutes Or so all you will be peeing is water

What stephen said is generally inadvisable for two reasons:

1. People who give drug tests regularly know about the "trick" of diluting your urine by drinking a lot of water. Often, if your urine is too dilute they will either say you have failed the test, they will send the test out for further examination, they will tell you to come back the next day (and to have non-diluted urine when you do, or else) OR they will make you wait until your urine has the correct properties.

2. Simply drinking water WILL NOT cause drugs to exit your body at an increased rate. The ONLY thing that determines the level of drugs in your body is your metabolism. You could take 100 mg of a drug and drink so much water that the pee every 30 minutes for 3 days. If someone were to then take an undiluted sample of urine or a sample of blood from you they would find that the amount of drug in your system is consistent with what should be expected even without drinking water. And if that drug were methadone and you waited until your urine was undiluted, you would test positive.

Water WILL NOT WORK unless the testers don't care about diluted urine. And many do.

Same thing happened to me. I take Nucynta, Soma, Buspirone, triazolam & Coumadin (a blood thinner) I needed a urinalysis & it came back positive for Methadone. I have not taken Methadone since 2008. How could this possibly test positive? Is it possible that I'm getting a false positive because of the Nucynta? I am so upset because I am being threatened of having my probation revoked. I hated taken the Methadone back then since it never help with my pain. So why would I take a drug that has been expired for 7 years. My dr has to do give me a specific urine test for the Nucynta. Is there a possibility that the standard urine test could have given me a false positive?

My doctor said my urine lab tests came back positive for methadone. I have never taking it in my life, but I have been taking nyquil. Can this be the cause for my false positive on my lab results?
