We use the RHS-1 (Hacker/Milestone) with vacuum to process fatty tissue and the RHS-2 (Hacker/Milestone) to process biopsies, .  We ran duplicate blocks (one for the microwave and one for the VIP processor) for the majority of tissue types.  The medical director was given the H&Es for a side by side comparison.  We also tested our most common IHC stains and DNA ploidy on the microwave processed tissue.  After the medical director reviewed all of the slides we were given the green light.  Many of the pathologist did not even know about the switch and could not see a difference.

Mary,
What instrument are using? Did you have to perform correlation studies? And finally, how did the pathologists do with the change?
