I took drug test today and it was positive for tca, I regularly take an OTC sleep aid with diphenhydramine. Couldn't have caused the false positive?

I took drug test today and it was positive for tca, I regularly take an OTC sleep aid with diphenhydramine. Couldn't have caused the false positive?

"tca"????: Did you mean THC (marijuana or cannabis)? TCA medically usually means tricyclic antidepressant, and these are actually chemically similar to benadryl (diphenhydramine). If all that was done was a SCREENING test, there are lots of potential false positives, and if used for legal purposes, all screening tests should be confirmed with a more sophisticated test, usually gas chromatography/mass spectroscopy. ...Read more

Nothing to do now: Nothing to really do at 10pm at night. I would say just tell the lab what happened but do you really want to tell his new employer that you're "loaning" your son YOUR drugs to help him sleep better? ...Read more

Taking Effexor (venlafaxine) XR cause me to test positive on a drug test? I have been on Effexor (venlafaxine) XR for 3 years.

Taking Effexor (venlafaxine) XR cause me to test positive on a drug test? I have been on Effexor (venlafaxine) XR for 3 years.

No: Drug tests are usually looking for specific drugs of abuse. They don't check for any and all drugs you are taking. The only way Effexor (venlafaxine) will show up is if they specifically look for effexor, (venlafaxine) and there is no good reason for them to do that. ...Read more

What to do if I had a false positive on a drug test, is there a chance I'll still get hired?

What to do if I had a false positive on a drug test, is there a chance I'll still get hired?

Not if they think it: Is positive. Companies that operate ethically should have a drug testing policy that requires confirmation of any positive on a screening test. The confirmatory tests, at this state of their development, DO NOT HAVE false positives. If you tested positive, and they confirmed the test with a sophisticated method the way they should, it means YOU USED THAT SUBSTANCE. So I would say stop using. ...Read more

Will the fat burner atro-phex cause a fales positive on a drug test will the fat burner atro-phex cause a fales positive on a drug test

Not sure: I tried looking up the ingredients, but could not find anything to tell me specifically what is in it other than caffeine. Unfortunately, drug tests are not entirely specific and some products may have amphetamine derivatives. All I can say is bring the bottle in when you go for your test and let them know you have been taking it. ...Read more

Could ibuprofen cause a false positive on a drug test!?

Could ibuprofen cause a false positive on a drug test!?

Mostly for THC: But ONLY on the screening test, and NOT on confirmatory tests. If whoever is doing the testing only uses screening tests, and does not confirm the positive test with more sophisticated methods, they are not following generally recognized principles of drug testing and could be subject to lawsuits. The confirmatory tests can determine that the positive is NOT a substance of abuse. ...Read more

Can vitamin B2 cause a false positive on a drug test?

Can vitamin B2 cause a false positive on a drug test?

No: I thought this was a strange question, but in researching it found out that this is claimed on some websites. However, I am quite certain that b2 does not cause a false positive on drug tests. It can make your urine bright yellow & some who drink a lot of fluids to dilute their urine before a test will sometimes take b2 so the urine looks yellow rather than clear. Will not cause false positive. ...Read more

Could you test positive on a drug test for being around only marijuana smoke?

Could you test positive on a drug test for being around only marijuana smoke?

Yes.: If marijuana smoke is in the air, you're breathing it. And, it is absorbed thru your lungs, even if the joint is not in your mouth. The dose is much higher for the one doing the toking, but often there is enough absorbed in nearby persons in a closed space to test positive. And a positive test can last a long time (up to 4wks depending on exposure). Best idea: step away if others are lighting up. ...Read more

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

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

Not likely: Most drug tests use a first test, TLC or thin layer chromatography, as an initial screen. This test is prone to cross-reaction or "false positive" results for some substances. Usually if the TLC is positive, a second test, gcms or gas chromatography mass spectroscopy is used to confirm. This test is much more specific for specific molecules and not likely to yield false positive results. ...Read more

Will drinking Chia seeds in my protein shakes cause a false positive on a drug test?

Will drinking Chia seeds in my protein shakes cause a false positive on a drug test?

Highly doubt it: Chia seeds are very healthy (see https://www. Nlm. Nih. Gov/medlineplus/ency/patientinstructions/000727.htm)
Searching online I saw one report of someone claiming chia seeds caused then to test positive for opiates, and saw that a colleague here states chia can cause positive tests- but she didn't give a reference. I see no other evidence or reason why chia seeds should cause a false positive test. ...Read more

Can naprelan (naproxen) or aspirin per day use cause a false positive on a drug test that includes testing for marijuana test?

Can naprelan (naproxen) or aspirin per day use cause a false positive on a drug test that includes testing for marijuana test?

Yes Naprelan (naproxen) can but: Apparently Naproxen (naprelan) can rarely cause a false positive on some marijuana screening tests. If this happens you can ask for it to be confirmed with a more specific test which will show that the positive was actually false.

Hi there, I took 3 30mg oxycodene pills Tuesday at 3:00 am. Will I test positive for that for my drug test tomorrow at 10:00am?

Depends: Assuming you are writing this on Thurs & your test is Fri, 79 hours after ingestion. If you took oxycodone your test will probably be neg but that was a huge dose and if you are small and not well hydrated it could be positive assuming they even test for oxycodone since many don't. If you took OxyContin you will likely be positive, again assuming they test for oxycodone. Opiate test will be neg. ...Read more
