Was this a mass UA or did they only test you..how soon after they tested you did you get the results?

Morphine is an opiate narcotic, so that explains the positive result there and, additionally, on the less expensive non-certified tests, it can cause false positives for other substances. This has been known to occur anywhere from 4 to 50% of the time.

Learn more Morphine details here.

Did you let them know you were given the Morphine, when you had the drug test done?

Morphine IS what is tested when testing for opiates, so of course you tested positive. Not sure about the cocaine.

I just went to the ER on Saturday after falling in the shower on Friday night. Messed up my back bad. They took a urine sample and said it was to see if there was blood in it to watch for any kidney issues. Never told me that they were doing a U/A. Then when I called back on Sunday to see if I could get something for the pain because naproxen was not even touching the pain, she tells me no because cocaine came up in my test. I don't use and it is clearly a false positive but they never even gave me a chance. So I went to another doctor at the clinic and that doctor let me retest. Now I'm waiting for results. UGU!

Based on my research, Morphine has been known to frequently test positive for opiates.

Although I haven't come across any specific details suggesting a cocaine false positive, I do believe that it's still a strong possibility due to the faulty standard drug tests they use today. A lot of these standardized drug tests have a fairly high false-positive response, where it seems as though anything is likely to show up. To my knowledge, false positives are known to occur on them anywhere from 4 to 50% of the time.

Have you asked your doctor about getting re-tested? I hope you can get this sorted out! These false reports just put too much stress on patients who are simply taking their medications as prescribed.

there are medications and substances that cause false positives and there are many that will show up opiates and although the persons giving the test will still say it does not make mistakes, that is not true. Some of the things that cause a false positive for cocaine are tonic water, amoxicillian, and the more I research,the more I find. I too, have recently tested positive for cocaine but did not have any use of cocaine. I was given lidocaine this past week as an anestetic and I do believe that is what caused it. A second test should be done, using a GC/MS test which is more accurate but many places that say they give a second test, do not actually use the GC/MS test but a different second test. If mine comes back as beng dirty, I will go to prison, for this test on me was done for parole, and knowing this, I would be a fool to actually use cocaine but now everyone will not believe me for I am a felon and have used, but very long time ago, nothing ilegal recently. The tests have their problems as well as persons that falsify paperwork or I have even seen persons swap urines, having been around testing many years. You have to be careful and be sure that a second test is done, watching who handles the specimen and knowing the proper chain of custody.

I believe you. I also believe it is not possible to watch your urine from the tap to the end of the second test to be untainted. Justice and honor and clean UA is for people who can buy them. Facts, like we have not used in the last decade, be damned. I have stage 4 cancer, I'm terminal so I have no reason to lie. Going back to prison thoughts, I'm guessing works better than a NA meeting for you. My pain doc buys her supplies from an unethical co. called Millennium, who supplies the 12 point urine cup with the strip in the lid for reading in 5 mins. The company then (supposedly) has the urine sample shipped from Seattle, WA to San Diego Calif. for "100% accurate, no mistakes confirmed test results." I found they have made a mistake on saying I am positive for cocaine. For sake of argument, lets say my failing heart and lungs tolerated some cocaine without sending my hypertension into a stroke or bleeding in my head.....they don't even use the gold standard to check the positive results by GC/MS. Their back up method of confirming illegal drugs is using another one of their leaky cup with supposedly what is left of my urine. I urinate in a bathroom where I'm forced to balance the cup and lid, which my fingers now touched the inside of, after touching how may doors, and elevator buttons before? Oh I could use one of the two urine collection pans one puts under the toilet lid to make collecting and pouring my urine easier. Which one do I choose...the one that obviously has some black cola appearing residue, or the one that is just wet, like it's been used and rinsed, left to dry. Try holding the cup, lid, dress and panties all at once. Sorry I can't keep the lid and cup sterile. I then am just a number on cup, put in a pass through cupboard along with the patients before me. I already can read the results on the lid and it's negative for all drugs, except my prescribed drugs. I then wait for a room and wait for the MD and 90mins to 2 hours pass. Yes, the results are ready in 5 mins. I'm told I passed. 2 months go by, my next visit BEHOLD I was positive for cocaine 2 months prior. The fact that I sat in your office for 2 hours, talked to you 3 times before my visit, and asked questions that required you to look in my chart, in that 2 months, and no mentions of a positive came up. MD even gave me a refill on meds. MD said I would have to talk this over with Millennium who does the tests. The lab refused to talk with me on 7 occasions, because speaking with me, the patient, about MY results broke HIPPA. They also ran a second confirmation that my MD and Millennium claims in 100% accurate. Not the GC/MS test but another pee in the cup with leftover urine from 3 states away and 2 days old. I can confirm this accuracy how? I'm disgusted and not bothering to go back to this MD. The only thing different in my life the past 2 months.....is the large investigation into this MD for insurance fraud reported by me. How do I keep the second test chain of command clean?
