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.
If you're worried you may get a positive urine test, and it was 2-3 days or more, since the use of the drug, I wouldn't be too worried. If you were to try some of the anecdotally successful ways of beating the tests, you may be successful. It's been reported that drinking a lot of water can make a difference.he results really depend on the sensitivity of the test. Tests that are more likely to show the presence of opiate metabolities, can be more expensive and require more work in the lab, thus making the test more expensive.
