Basically its impossible... Simethicone is an anti-foaming gel that is not absorbed by the body or your GI system into the bloodstream. Its also considered relatively safe & there are no known side-effects. So, No, it certainly shouldn't test positive for anything. Even If it did (hypothetically) the confirmation test would EASILY detect the specific one so no worrys.
Aside from oxymorphone itself, when oxycodone is metabolized, one of the metabolites is oxymorphone.
No
can periactin show up positive for drugs in urine
no
Oxymorphone(Opana) is metabolized in the liver to 6-hydroxyoxymorphone and oxymorphone-3-glucuronide. Oxycodone is metabolized to α and β oxycodol; oxymorphone, then α and β oxymorphol and noroxymorphone; and noroxycodone, then α and β noroxycodol and noroxymorphone (N-desmethyloxycodone).[2] (14-Hydroxydihydrocodeine that in turn becomes 14-Hydroxydihydromorphine) As you can see both drugs metabolize into many different variations. When it comes down to an ordinary drug test, all these variations can be tested for and distuinguished from eachother, but the test results itself may just show positive for Opiates, or it may display the metabolites as well, indicating both Oxymorphone and Oxycodone use.
Mixing water with urine from a pregnant woman will not affect the accuracy of a pregnancy test result. The presence of hCG hormone in the urine is what determines a positive pregnancy test result, not the addition of water.
CONCLUSION. Because naloxone hydrochloride is structurally similar to oxymorphone and its metabolites are excreted in human urine over several days, its potential to cause a false-positive opiate screen on standard urine drug screens is of concern.
Smoking marijuana.
if you breathe enough of it
Making has without gloves can cause a positive urine result if it enough is absorbed into the skin or some of it is accidentally ingested. Has is designed to be smoked but can enter the body from several means.
Gmelin's test is a qualitative method for demonstrating bilirubin in urine. Positive means bilirubin is present.
A test they don't run can't possibly be positive.
