What Can Cause False Positive Benzodiazepines (Top voted first)

Updated

I am currently prescribed 60mg Fluoxetine, 20 mg Abilify and 10mg Zolpidem, along with 15mg Mirtazapine. I have tested positive off and on for benzos since beginning Zolpidem in June. I tested positive at 1:30pm and negative at about 6:30pm. My urine test was sent to a lab. Why does this keep happening? I am on probation and do not want to go to jail!

My daughter was in rehab for drug addiction 2 years ago and has been drug tested weekly since then and has had no problems. Early this year she was diagnosted with MS and is currently taking various meds. for MS related problems. This week her urine test read positive for benzos. She has not taken any and this was not her drug of choice when she was addicted. They are giving her till Monday, 12/10/12 to come up with some proof that she did not take any. If she doesn't, she will be sent to jail for 6 years. I will give you here a list of what she is taking and perhaps you will see that one of these drugs can result in a flase positive for benzos:
ALEVE- much for pain
PHENAZOPYRIDINE
NITROFURANTOIN
CEFADROXIL
FLUCONAZOLE
REBIF - injection - 3x per week for MS
By the way, today's test was negative but they are still going to judge her based on the false position urine test
from Monday.

I am also testing positive for diazepam (Valium) even though I don't take it. I take Ambien at night and Prozac and Abilify. Could these be causing my false positives for Valium?

The urine drug *screen* is a screening test. Screening tests are selected/designed for their high sensitivity. The more sensitive a test is, the more prone to false positives it is. -- Consider an earthquake sensor. A very sensitive earthquake sensor will detect the tiniest vibrations, even if it's not really an earthquake. Maybe it's just a really heavy guy walking by.

Positive urine screens need to be followed up with a confirmatory test. Confirmatory tests are chosen for their high specificity. They detect specifically what they are indended to detect and preferably nothing else. -- Continuing with the earlier example, the heavy guy would *not* be able to set off a sensor that's specific to earthquakes.

Any halfway competent clinician should know all about the pitfalls of screening tests and the need for confirmation. It's why they often say more testing is needed, and patients get frustrated that they can't get a straight answer.

As for law enforcement, they probably also know false positives are likely, but use the situation to create anxiety to make confession more likely (law enforcement tends to not care about actual guilt). Anyone in a situation where they can potentially lose their job or freedom because of a screening test without confirmation should hire a lawyer.

Zolipem or Ambien can test positive for Benzo. I am a nurse and have been random tested for years. I never tested positive for anything until I took Ambien CR. I was cleared at work because they are aware that it can test positive, but of course I had to bring a note from my doctor and my script to prove it.

I tested positive for benzos I honestley didn't take any. I obvs. Told them it was impossable and asked if I could somehow send it away to be re-looked at, on doing this it came back negative :) Yet they are now saying there's 5 diffrent benzos(I no about temazepam etc ) but surely if there testing for benzos a benzo is a benzo?? The doctor stated that I must of taken a illegal street valium which I clearley didn't at 6months pregnant, and still stating it came back negative, yet won't have it that I havnt taken a street valium? I'm confussed as when I try and challenge it as I no I honestley havnt taken anyything, I'm getting treated like I have taken something!!:( Does anybody know what I could do to get a straight answer and where from as I'm not getting1 from my local C.D.T as my unborn child is looking to be put on the at risk regioster threw this reading as I'm being accused of abusing benzos in my pregnany even though I've asked for a hair strand to prove it, it was a swab that came back.

This to happend to me except I had stopped taking pre-gablin 6wk previousley I knew I hadn't taken any so challenged it resulting in the swab being sent back it came back a new reading as negative, as I was about to say "I told u so" to my keyworker, she beat me with "there's 5 benzo'sdiffrent 1s temezepam, diazepam etc. It must be one of them or a illegal diazepam u took" I was furious as I thought a benzo was a benzo (including 5 diffrent ones) and a new negative reading was a new negative reading! So I'm furious!
