In regard to case mix-ups, what is currently being done in situations where practices do subspecialty sign out (for example practices that do ONLY skin, breast  or prostate?)  In these labs, the only option is to have specimens of the same type back to back.  I think this situation is even more dangerous when slides are pre-labeled?   Any insights would be appreciated.
