Re: [Histonet] H&E slides for HT practical exam

I agree with Peggy.  It is better to learn to be flexible and 
do excellent work than adhere to policy that only produces a ridgid stain
The goal is to produce slides that are of the highest quality for each tissue
and stain.

Unforutnately we have seen and heard from people taking the test for ASCP
in Histology who cut the same blocks and stianed the slides at the same time
when one passed
and one failed.  I have yet to see anyone on the grading committee address this

Sorry to open this can of worms again however, when I took my test in the "70s I
was told
not to submit any animal tissue (I was doing research on animals only) or I
would fail.  I know
that has changed and I did find a way (pre-HIPPA) to get my tissue and stain but
it shows the differences 
in how we are treated and graded over the years.  Other than what you stated 
for H&E is there a true
standard for each stain or does it depend on the person grading and what they
like or see.
