Jennifer,

I understand the comment about two people sectioning differently etc and
staining can look different even when sections are all stained together on a
stainer.  However, when the pathologists who reviews (for students) the same
sets of slides and see no difference it is not as clear cut as you see it.  I
have been seeing and hearing the same story for years and ASCP does not clarify
beyond a description what they want.  What I have never understood is why the
guidelines for histology registry have not been clearly defined and with the
number of people grading given a standard of stain/slides to work from.

I am sorry that in my opinion.   ASCP takes our money and wants us to register
and doesn't take as much time for a critical to care area as they do for other
areas of the clinical and research laboratories.  I have not ASCP to either
responsive or caring about our field over the almost 30 years I have been
registered.  They only get my money yearly because they are the only current
body with a national register and I have always done CEU so that is not an
issue for me.
