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.
Heroin and other opiates such as morphine and opium are detectable by standard drug tests on urine between 24 and 48 hours after use.A urine test is the most commonly-used method, since it is both relative inexpensive and easy to administer.rine tests are not the only testing method used to detect the presence of opioids. A blood test will reveal the presence of H or other drugs in this class in a person's system. This testing method is more expensive than the urine test, and requires trained medical personnel to collect a sample.
