Can Ambian Cause A False Positive For Methadone

kikileigh Says:

I take Ambian to help me fall asleep as well as Oxycodone for chronic pain (along with other prescribed medications for bipolar/manic depression (Pristiq), anxiety disorder (Ativan), Fybromialgia (Lyrica), migraines (Fioricet), and muscle relaxers (Soma and/or Zanaflex). Will any of these (or a combination of them) cause a false-positive for Methadone in a UA? I need a FAST answer!! Thanx!

NO URINE Screening test, and/or EIA or IMMUNOASSAY test is 100%, there are some cross reactions, and many false positives and false negatives. That is why it is required to CONFIRM all positives by an alternative methodology, preferably LC/MS/MS. It is expensive to run, and most hospitals do NOT have the equipment or ability to confirm.
Good luck.

Dr John is there any 100% urine test? I had surgery 6/23 and was given meds in surg and post. A week later I tested + for methadone, something I've never took in my life. The lab is sending it off for a 2nd confirmation. I got a MAR from the hospital, which didn't show methadone and only took vicoden, antibiotic, and trazodone at home.
This could be extremely bad for me.
The only thing I can come up with is a false positive or I was given something in the hospital that wasn't charted.
I would never take something that like methadone. Help!!

With the medications that you listed, it does not seem possible that you would test positive for Methadone. If you came up with a positive screen, demand confirmatory testing, and that will give the absolute truth if done correctly.

I was recently in the hospital and the dr told me after i tested positive for methadone (which i've NEVER done) that trazodone can cause a false positive.
