False positive for BZO and BAR?
Hi. I recently went for a preemployment UDS. I came back positive for BZO and BAR. I currently take st johns wort for tension headaches and anxiety. I also take bentonite clay to detox from heavy metals. I take oregano extract for intestinal and acne purposes, and claritan for allergies. I also take ibuprofen for infalmmation. I was also on an antibaiotic generic for BactrimDS. As you can see, I am a bit of a greeny and am totally against prescription medication, if it can be avoided. Define Irony. Would any of these cause a false positive for BZO and BAR? I am going to get my dream job.
AskDocWeb: Sorry Momma, none of the products you list have been reported to cause a false positive for either benzodiazepine or barbiturates. However, that doesn't rule out the possibility of a false positive. You would have to get a confirmation test (gas chromatography-mass spectrometry or GC/MS for short) to find out if your test result is really a false positive or not.
False positive for meth?
I was wondering can a diet pill called Phentermine cause you to be dirty for meth? I came up positive for meth, I told them all I've taken is my diet pill. They said they checked and it can not cause you to be positive for meth. But I disagree considering I know I have not used this drug.
AskDocWeb: According to Redwood Toxicology Laboratory Inc. (RTL), Phentermine is a cross reactant for methamphetamine on urine drug tests. RTL is one of the nation's premier forensic drug testing facilities. The results of their drug testing provide legally defensible results. They sell millions of instant urine tests and oral fluid drug tests each year. They are THE experts so they know what does and doesn't cause a false positive. You might ask whoever is doing the testing where they get their drug tests. If it is RTL then they should know better.
Is this true?
Hello I just went in for an interview and he did a saliva drug test. Someone told me that i have a good chance to test positive for meth because i take meds. I do not do or be around any drugs and very rarely drink. I take Metformin, fluoxetine, oxycodone, and fluticasone Propionate (Flonas). I have also been sick took nyquil and sudafed for the past four days and nights. Is this true and if so will they be able to tell that is was legal use and not illegal drugs? Please help i need this job or i can lose my house.
Scared of the possibility
AskDocWeb: Anyone taking prescription medications has an increased risk of getting a false positive result on a drug test for drugs of abuse. That does not mean that you will, just that you need to be prepared for that possibility. This is the main reason for disclosing all medications, both prescription and over-the-counter, that you are using before taking the test.
If you get a positive drug test result and you know that are not abusing drugs, be aware that the results of the drug test are "presumptive" (they consider you guilty) until proven otherwise. In order to disprove that assumption of guilt the original sample must undergo a confirmation test. In some cases you have to demand that test and pay for it yourself or you are labeled a drug abuser. Be prepared to stand up and defend yourself.
I am currently on probation in North Carolina. What are the drug tests like (the standard dipstick ones all the way up to most advanced) and what can they test for?
Also I am taking etizolam i am especially worried will this cause a false positive for benzodiazapines for any type of test they do?
I know there is a whole range of test types and degrees of strength so would any kind of test prove this is not a real benzodiazapine or does every kind of test cause a positive for benzos. Please I need to know quickly? And also will suboxone likely be tested for(i know it can but ive heard its expensive and extra?)please respond asap and try to answer each of the questions if possible thanks so much.
AskDocWeb: An answer to your first question, "What are drug tests like?" would require writing a book, which we don't currently have the time to do. Etizolam is not a benzodiazepine. It is a thienodiazepine, which is a benzodiazepine analog, a small but important difference compared to a benzodiazepine. Theoretically it would not show up on common drug tests however, there are antidotal reports of it testing false positive for benzos. So far we have been unable to find documentation to confirm that possibility. There are specific tests for etizolam but common drug tests for drugs of abuse do not test for it.
You are correct about suboxone. According to American Association for Clinical Chemistry, suboxone may test false positive for oxycodone on urine drug screens but that does not occur on all tests. There is a special test that tests for suboxone and in some places it has been reported to cost up to $500. Because of the cost it is typically not test for unless there is a specific reason.
If you believe your test results in a false positive then additional testing is required on the original sample to confirm or deny the results. Typically that is done with either a Gas Chromatograph/Mass Spectrometer (GC/MS) or high-performance liquid chromatography. Both of these tests are expensive but may be worth the costs to prove your test result is a false positive.
Tested positive for bzo
I got in a fender bender on the job and tested positive for bzo. Hopefully not an issue w my employer because the med was prescribed to me. I told my employer about the bz so will they likely to send the sample for gcms anyway? I already feel embarrassed - having to let them know I had treatment for anxiety - I hope they don't think I'm too weak to do my job now or something along those lines - I guess the gcms will show all meds I'm taking? I also take phentermin, prozac, lisinapril, crestor, metformin, norvasc, aspirin, adviar and singular. I don't want my employer to know everything about my med conditions. They don't affect the way I do my job. I get on w everybody at work and do a good job - even chosen to train new people. I don't want them to look at me different or treat me different because they think I've got stuff wrong w me. Also can the gcms show how much bzo in my body? That would work out good for me because it would show that I took the bzo the night before work and not on the job. I took 1mg atavan and put the ding in the vehicle about 14 hours later.
AskDocWeb: They are unlikely to send your sample for confirmation testing unless something shows up. The GC/MS test will show all the medications in your system at the time of the test. It is accurate enough to specifically quantify exactly how much of each one is in your sample.
Tested positive for THC
I take kolonapin but tested positive for thc. I dont d smoke pot. have u ever heard of this?
AskDocWeb: Kolonapin has not been associated with false positives for THC however, there are over 70 possible causes for that kind of false positive. If you are convinced that your drug test result was a false positive then we suggest you get a GC/MS confirmation test.
