I have been thru 2 CAP inspections and have never seen that question.  The
important aspect is that the positive control tissues stain appropriately in
your laboratory.  If one of my pathologists has a question about an IHC
test, we send a few of the tests in question to be validated.  I would think
it would be the decision of the pathologist in charge and what he/she is
comfortable with.  Then there is the issue of billing, payment, etc., but
that's another subject.
