Hi All,
We have just been asked to start doing ER/PR on FNA slides.  My question
is, what do we use as controls?  A  paraffin block does not seem to be
an appropriate contol for a fluid.  We do not work in a hospital or a
histology lab.  We are in a reference lab in which the already embedded
blocks come to us for immuno staining.  We just cut the slides and
perform the immunos, so access to FNA fluids or fresh tissues is not an
option here.  We do have a Shandon Cytospin here.    Any ideas or
comments will be most appreciated.
