    SWIM recently had an injury using a table saw, which caused them to lose their left middle fingernail and a good chunk of flesh surrounding it (it didnt't hit bone so, fortunately, they still have their whole finger). SWIM went to the ER on saturday night and learned the tip of that finger was also fractured. SWIM was prescribed 18 Oxycodone (5mg-325). SWIM gets drug tested once a week and is only allowed to take narcotic medication if it is prescribed and absolutely necessary, which it was. A few weeks ago, SWIM was given about 60 Hydrocodone pills by a friend and was saving for when they no longer have to get drug tested. Now that SWIM has an excuse for testing positive for Oxycodone, is it safe for SWIM to take some of those Hydrocodone too, or will the drug test be able to tell that they took something other than the Oxycodone they were prescribed? The test is usually a dipstick test but there is a chance the sample will be sent to the lab. Thanks for any advice.

    it depends on what specifically the test looks for. hydrocodone breaks down into hydromorphone, so a test that looked for it would test for hydromorphone. oxycodone, on the other hand, is broken down into oxymorphone, so a test would look for that. it is pretty rare that a drug test would be so comprehensive as to test for both of these substances. but to answer your question: yes, a drug test has the ability to tell the difference. it is just somewhat doubtful that it would do so since a standard opiate test only looks for codiene and morphine.

    but if they are going to test him when they know he is going to test positive for opiods then they will probably use GC/MS analysis to find out if it something other than oxy. swim recomend not risking it.

    SWIM has seen even very simple 5-6 panel drug screens that have both "opiates", which SWIM guesses is anything that breaks down to morphine, and ALSO tests for oxycodone (by detecting oxymorphone).

    On the other hand, SWIM has passed a drug screen for opiates on at least one instance when taking only hydrocodone, and lots of it... guess they didn't test for it... but he was lucky... better not to risk it IF the results of the test are important for SWIY.

    As I said there more likely to test for it because they know you are going to fail the test. They are smarter then you think.

    Hydrocodone is excreted into the urine as hydrocodone, hydromorphone, and/or norhydrocodone.

    Oxycodoone is excreted into the urine as oxycodone, oxymorphone, and/or noroxycodone.

    All are easily distinguishable and detectable by modern chromatographic/mass spectrometric methods.

    The scope of analysis is very lab-dependent.
