STRANGE. I HAVE HEARD THAT UNLESS THEY ARE LOOKING FOR METHADONE , IT DOESN'T SHOW UP. LET ME KNOW WHAT YOU FIND OUT. KIMMIE
Many drug test don't search for Oxycodone or it's byproducts. The Phlebotomist may have ordered the wrong drug screen. It also depends on how often you take the medication and when. Hope this helps.
