No it does not show up in a standard test for drugs of abuse. There are some dipstick tests where it has been reported that suboxone caused a false positive for oxycodone but when those urine samples were sent to the lab for full analysis they were negative for oxy. They are developing tests for suboxone, but right now to specifically test for it is very expensive. If you're just taking a standard drug test, it won't show up.
i take 2 tests a week - both test for suboxone as well as every other drug you can think of (except crystal meth & ketamine). the cost of each test is ¬£28. Again - i suppose its all down to 'why' you're being tested.
