If you are running something like a liver panel, the PAS or PAS-D has an
internal control. When running a PAS-D, you should run a PAS for
comparison on the same tissue.  If you are running... lets say skin for
fungus or something, then yes... always a control.  At least that is my
procedure...

When performing a D-PAS stain, do you run a PAS control also?  With or
without patient tissue?
