DXM and Drug Tests
by Erowid
Tested for in Standard Drug Tests? NO 
Tested for in Extended Drug Tests? NO 
Possible to Test for? Yes 
Will Trigger Tests for Other Substances? Possible : PCP & Opiates

... False positive is pretty rare, More than likely if shes truthfully not taken anything then shes been drugged at a party or something and not realised it, Might want to pass that by her, Because if shes not lying and failing a test then id be worried wtf went in my system with out me knowing it
