I've read the interesting discussion about microwave processors and have a
general question. Nowadays there is the demand of standardization in
histolabs. From tissue to tissue and from lab to lab we have to minimize the
differences in processing the specimen. So tests like immunohistochemistry
can be performed in high standards and reliance. 

How do labs match this issue when introducing a new technology like
microwave processors? Do they use old and new processors parallel? Can you
run all sorts of tissue with it? If this isn't possible, are there two
"kinds" of paraffin-blocks to make fitting protocols? 

What about these FDA-proved tests? After all the work you have the lab-own
standards, but aren't "allowed" to do the official test?

I think about biopsies, that are partly proceeded in microwaver, partly in
the old instrument over night, specimen fixed in formalin for few hours up
to a week, or fixed in a new reagens without formalin,....

 

Perhaps someone could share her/his experience with us.
