Question 1

medical conditions such as hepatitis-c and cirrhosis of the liver can also cause inaccurate urine drug test results.

Accepted Answer

Unlikely: Liver disease would not interfere with the confirmatory drug testing.

Question 2

will smoking e-vapor cigarettes with proplyene glycol cause a false positive for thc on a drug test?

Accepted Answer

Doubtful : If it did, you'd likely have already heard about it.  Parolees on drug tests are usually told not to eat poppy seeds though because it can cause a positive result for opioids.

Question 3

can plaquenil cause a false positive for thc on a drug test?

Accepted Answer

Possible?: Acriquine is on a list of drug interference medications and it is a derivative of chloroquine also. drugs.com
I have not been able to locate any information to confirm that concern. If a positive(false) does occur requesting a more sensitive test in a reasonable response.

Question 4

i take 40mg of omeprazole and i haven't smoked any weed in months. i have a drug test coming up, i've been testing myself at home and i've tested positive for thc. i've read that omeprazole can cause false positive? is that possible?

Accepted Answer

: If you have not smoked weed for months, the positive urine test for THC is likely false positive and it can be due to taking omeprazole. You should switch Omeprazole to Famotidine for at least a week before the test day.

Question 5

false posotive for drug test what can causr a false positive for thc on an institant drug test

Accepted Answer

A lot of products.: A screening drug test is not perfect. A site i would recommend for a list of over the counter medications and the associated false positives is: http://www.Askdocweb.Com/falsepositives.Html.

Question 6

can having hep c cause a false positive urine or swab drug test?

Accepted Answer

What drug was tested: Hep C per se should not give a false positive drug test, however, it begs the question, how did you get Hep C? Were you abusing intravenous drugs?
If you have Hep C, get treatment as it is mostly curable now.

Question 7

will flexeril (cyclobenzaprine hcl) give you a false positive on a drug test? i have recently been prescribed flexeril (cyclobenzaprine hcl) and took a drug test and i failed it. i do not do drugs and it showed up as thc why is this

Accepted Answer

Through : Through my research on this question, it appears that Flexeril (cyclobenzaprine hcl) will not cause a positive thc result. One common medication that causes a false positive thc is ibuprofen. This is found in advil, motrin, and nuprin. So if you have recently taken any of these that may be the problem.
I also recommend that you ask for a copy of the test. Make sure the name, id number, and any other iddentifying information matches up.
Good luck.

Question 8

hello. can omeprazol give a false positive for a orine drug test of thc, cocaine, or anfetamines? i have been taking it for 2 weeks (20mgs per day).

Accepted Answer

Not likely: Although many drugs can cause false positive screening  tests, any positive must be confirmed by gc/ms and their are no false positives with this test.

Question 9

i take 500mg of naproxen 2x a day, i keep seeing it causes false positives for thc on urine drug test, is that true?

Accepted Answer

: Yes, non-steroidal anti-inflammatory drugs (NSAIDs) such as naproxen or ibuprofen can cause a false positive test for THC or barbiturates. Oxaprozin, another NSAID, can cause a false positive test for benzodiazepines.

Question 10

can you tell me if i'm getting tested for hepatitis c/antibodies does it also test for thc?

Accepted Answer

No: Drug-testing is a specific test, usually of urine, and you must be informed that you are being tested in most (if not all) states.  The test for hepatitis c antibody is a blood test that is specific for that one problem.  If your test is positive, further testing needs to be done to determine the activity and extent of the hepatitis c infection.  There is evidence that marijuana may damage liver.
