http://www.occ-doc.net/_disc4/0000001a.htm and see table IX here: http://www.drugcheck.com/_main/images/DrugCheckStudy.pdf
according to Table IX and as described in the text "Oxycodone, oxymorphone, tramadol, meperidine, nor-meperidine, nor-morphine, nor-codeine, and buprenorphine showed no interference at 50,000 ng/mL". That is, at those concentrations they did not yield a positive immunoassay result for opiates.
I hope this helps.
