I work for a drug rehabilitation center.  We also conduct urinalyses for some local drug courts.  Yesterday I had a client come in for testing who had a script for hydrocodone.  She tested positive for opiates as expected.  However, we are also running an Oxycontin test.  In my opinion she tested positive for oxycontin too, but my co-worker saw a very, very faint line.  I marked it negative based on my co-worker's observation but still had my doubts.  Can hydrocodone cause a positive result on an Oxycontin test?  Please explain in the most simplest terms as I am not a medical tech nor a former addict.
