Re: QA Daily H&E's

From:Pauline Burton <>

We are cutting 600 to 800 plus slides a day.  Our QC method is to make a 
block with colon, skin and umbilical cord in it.  We stain one each day 
before staining the slides.  This tells us several things.  First, that our 
stain set-up is working.  The solutions were all placed in the right spaces. 
  You can see that everything looks good macroscopically.   Second, it tells 
us microscopically about the quality of the staining and if all tissue 
components are staining correctly.  Third,our pathologists do not like the 
mucin staining the pale blue color.  The umbilical cord is a quick indicator 
to make sure that is not happening. Since we do a great deal of GI biopsies 
and skins, those two tissues are included in the control.
