Opana And Drug Testing

Adam Says:
I am sick of never seeing good information online and at how inaccurate most of the stuff was that I came across when desperately searching for answers myself. So, what follows is what I know about Opana drug testing. Everything here is accurate, and learned first hand. It's not vague, and there are no guesses, no assumptions, no generalizations. I know from experience, dude, if ya know what I mean....

Opana (oxymorphone) is detectable in urine anywhere from 48 to 96 hours (2 to 4 days), depending on dosage, length of use, and the person's size and metabolism. The quickest I have personally gotten it below detectability without diluting it is 60 hours. I have tested positive before after 55 hours clean, also.

I know a little bit about opana drug testing because I have been on a drug court program as well as strictly monitored probation and opana is my drug of choice, so naturally through experimentation and testing the limits, I have both passed and failed several tests. My probation department uses Redwood Toxicology Labs (CA) for their testing, and this much I know about Redwood:

A standard issue test from Redwood (can be either a 5 or 8-panel, doesnt matter) does NOT test for opana. This is the test that is given to most people in my county's probation office.

Redwood also has a ten panel test, and something called a P40 test, the latter which can test for virtually any drug out there, including opana. The ten panel includes a strip for oxycodone, which is NOT the same thing as opana, but does not test specifically for opana.

However, a ten panel test HAS come back positive for Oxycodone for me in the past when all I had taken is Opana.

Most of what you can read online says that oxycodone metabolizes into oxymorphone, but not vice versa. So, technically, if you take an Opana, and are tested for oxycodone, you should NOT turn up positive for oxycodone. I am living proof that this can happen, that opana CAN show up as oxycodone, even in a highly accurate test. So if anyone is under the impression that they can get away with using opana if they are only being tested for oxycodone, be advised.

Technically, the only way to test for Oxymorphone through Redwood Toxicology (many, but NOT ALL labs' testing procedures are the same, so i want to stress that this is was the lab used) is to administer a P40 (the test for everything) or to specifically test for oxymorphone as a "write in" (where on a blank line on the sticker that goes on the piss cup, the administer can write in what specific drug to test for. this normally happens when they are looking for a drug that is not tested for on the 5,8, or 10 panel tests, but do not want to bother with the comprehensive P40, which is ridiculously pricey). Its important to note that if being tested for oxymorphone (Opana), then you WILL come back positive for oxycodone (Oxycontin) as well. That is a guarantee.

Your best bet is to drink lots of water in the days leading up to the test, but only about 48 oz the day of, to avoid a dilute (which any legal-type situation will treat like a positive) AND give yourself 80 hours clean.

Good luck.

Thank you for the valuable and informative post on our site, I am sure it will help many of our users in the future.

As to explaining the false positive for Oxycodone, when you were taking Opana, that directly refers to the quality of the test being used.

There are very few agencies that are required to use certified tests, most are free to go with the cheapest bidder and these cheaper tests aren't well known for their accuracy. What frequently happens is that one synthetic, or semi-synthetic drug causes a false positive for another.



Are there any questions or comments?

Hi Adam,

Listed below are a couple websites specific to locating pain management doctors in a given area. All you have to do is input your city or zip code for narrowed results:
{link removed because site no longer exists}

You can give this other page a try too if you come up with different results for some reason or another:

Alternatively, you can have your current primary care doctor refer you to a new pain management doctor or clinic.

Please post back if either of these links were able to work out for you. Hope this helps!

Can you or anyone else tell me for sure, that Opana won't come up as anything more then oxycodone?
I have to get urine tested soon and I'm allowed to be positive for oxycodone because I'm prescribed 2 10mg a day(oxycodone) and 4 10mg a day hydrocodone, due to my bad back. I just don't want the test to say I had anything else being used. I'm not sure what test the use but the do send it to a lab. I get a federal background check and all that, so I imagine they spend money on a good test.
Anyone with good information could really help me out.

Since you're incredibly knowledgable about this topic, can you please answer my question; if you've taken oxycodone, can it show up as opana?
I took a drug test at my PM office which resulted in a positive Opana result. I had no idea what it was & I've never heard of opana or the oxymorphone part-I thought they were saying morphine.
I understand that Endo Labs is the manufacturing company of Opana but the brand of oxycodone I had was also from Endo Labs, so I was thinkin they must fall into the same thing but then why would the test be so specific? I mean, it HAS to be quite the panel at a pain doctor right?
I'm so confused! I'd appreciate an answer or idea of what's going on :)
