CT scan done . DX with hydronephrosis. Wearing catheter. UA was done came back positive for cocaine. She has been in site for entire time. No illegal drug use was done. Now trying to take baby away. I need some guidance.

Expert:  Dr. D. Love replied 1 year ago.
None of these medicines are reported to cause a false positive for cocaine on a urine drug screening test. However, there are some people that can have a false positive urine drug screening test, even if no other medicine is being taken. Since there are false positives that occur on a regular basis, the usual approach if there is a positive screening test would be to then perform a confirmatory test, such as GC/MS. If the only evidence that exists is a positive urine drug screening test, then she or her attorney should be able to win the argument that no action should be taken until a confirmatory test is done. If that urine specimen was not sent for a confirmatory test, then she can offer to take another urine drug test or a hair drug test. The authorities may prefer a hair drug test, since it will include the period of time when the urine drug screening test was positive. If I can provide any additional information, please let me know.

Well I can't understand that nothing is causing a false positive due to the fact 2 days after admission to hospital she still tested positive for cocaine per a blood test per my request under the hospitals care with only visitor or contact is myself. I am a nurse and this doesn't make sense. She has hydronephrosis, Hep C and HSV. She also has an open wound from C-Section after 2 surgeries and a Foley catheter
I have done research and know that Ibuprofen can cause false positive. This makes no sense.
Expert:  Dr. D. Love replied 1 year ago.
Ibuprofen can cause a false positive for marijuana/THC, but it is not reported to cause a false positive for cocaine.
Customer: replied 1 year ago.
So what can cause false positive for cocaine other than drug itself?
Expert:  Dr. D. Love replied 1 year ago.
As I said above, there are some people that can have a false positive urine drug screening test, even if no other medicine is being taken. It is an intrinsic issue with the testing method. Therefore, the question is not what is causing a false positive, but rather whether it is a false positive, and the method by which it can be determined that it is a false positive is by doing the confirmatory test that I noted above. If you are a nurse, then you know that there are many rapid tests that are not as accurate as the gold standard. A rapid Strep test is not as accurate as a throat culture. A urine dipstick for leukocytes is not as accurate as a microscopic exam for leukocytes, and neither are as accurate in diagnosing a urine infection as a culture. The screening test for HIV is falsely positive some of the time, so that the confirmatory Western Blot test is routinely done to confirm the diagnosis. It is the same with urine drug screening tests - it is not as accurate and will sometimes have a false positive. This is intrinsic to the test and not necessarily because the person is taking something to cause the false positive. Certainly, there are some false positives that can be due to certain medicines, but even after all of the known reasons for false positives are excluded, there are still a fair number of false positives that occur. That is why a confirmatory test should be routinely done, such as a GC/MS.
