No they would not:
Just more misinformation, lol.
Call Cdex, make the appointment.
Find out which signatures the G4 has in its Library base.
Bring two or four or six or eight of those drugs.
Have them numbered, let the G4 do it's thing.
Then Cdex will send off samples of each 1-8 drug to an independent lab who has a mass spec, and let them identify 1-8 samples, and see if all the signatures match up.
And, they will match up.
