Trait controlled by the both environment and genetic factor. Usually, multifactorial traits outside of illness result in what we see as continuous characteristics in organisms, especially human organisms such as: height, skin color, and body mass.
I recently took a drug test for a job. I tested positive for opiates in my urine. I do not and have never taken drugs of any sort other than alcohol. I dont take any prescription drugs, how is it possible that this happened. I hade consumed some beer about12 hours before the test.
So sometimes oxycodone will show up on an opiates test, but not with the same accuracy as it shows up on an OxyContin / Vicodin test. The OxyContin / Vicodin test specifically tests for oxycodone in urine, so is much more reliable for that purpose than the opiates test, which detects morphine in urine.
