... any. This has happened several times. Any answers would be greatly appreciated
Methadone is closely related to propoxyphene and sometimes is the cause of the falsely positive. Also anything you ate with poppy seeds, cough suppressants containing DXM, and nyquil.
You should request a confirmation test be done to be sure the way your bodys metabolism is not processing the methadone at a rate that could show falsely positive for propoxyphene.
I go to a clinic as well and my first two urines came back with phenobarbital which I don't take. Good Luck and God Bless. Sable
Hi Josiekay. I thought you might find this article interesting. Also, you could request a new test with a new batch of kits. Many of the chemicals and reagents in these kits have a short shelf life and may be outdated. Good luck to you.
Laboratory slip-ups are to blame for many of the mistaken test results. But even perfect labs running perfect tests will also find many false positives.
False positives are caused by:
*Nasal decongestants such as Dristan, Neosynephren, Vicks Nasal Spray, and Sudafed, which cause false positives for amphetamines.
*Poppy seeds like those on a dinner roll, which cause false positives for opiates. Even the highest-quality test currently available, the GCMS test, still confuses poppy seeds with heroin.
*Pain relievers such as Advil, Nuprin, Midol, Trendar, or any medicine containing Ibuprofin cause false positives for marijuana.
*Antibiotics such as amoxicillin or ampicillin cause false positives for cocaine.
The above list is only a beginning. Most substances which people have in their blood have never been tested to see if they cause false positives. Indeed, even some natural body enzymes cause false positives. According to research validated by the Congressional Office of Technology Assessment, melanin, the natural pigment which makes skin dark, can cause false positives for marijuana.
