I guess in the question is another question. Was this a simple urinalysis in which case no drug screen would have been preformed. Trust me you would know if there was a drug screen being preformed on your urine; it is handled differently. The urine has to follow a whole 'chain of custody' routine. So if this was not done you probably had a simple U/A.
Also Percodan is a specific medication which is much less likely to come up on a drug screen than say a positive test for say a general test for opiates (which would be more commonly tested for).

Depending on how you take them? PRN or as needed may mean you only take them randomly. Does that mean you skip a day or more at a time? The metabolites are measured up to a certain parameter, hence, a negative is not a negative it simply means that you have not reached the drugs starting point for testing. So what the test is really saying is that you are not abusing them and your metabolites have fallen below the starting point for the test. Another possibility is that they are doing randoms and not testing for every drug each time, or if you declared that you are taking them they may have opted not to test you for it.

Probably because they did a urinalysis, not a urine drug screen. It's funny how the answer you get is so dependent on the question you ask.

A routine urinalysis does not check for drugs.

because if ur doctor prescribed them and gave u the ua then he probably didnt check for opiates since they would be in ur system

They usually only test for cocaine,meth and marijuana, however urine tests are fuul proof i have passed one before and should have failed it. Really it should be a violation of civil rights because they are not full proof.

working in a hospital before, i would say, either the lab paperwork was wrong or if the State was giving it, Who knows! They don't do anything right
