hazing H&E's



      Hope everyone had a great holiday...... now back to work......  Here in the past couple of weeks my docs are telling me that they are seeing a hazy bluish-gray artifact over some of the tissue.  I had to see it to believe it and sure enough there it was.  It almost looks like the slides are not being deparaffinized enough so we worked on that and the problem is still here.  I don't feel that it is a staining problem because it would be only 2-3 slides out of a days worth of blocks (100+).  We bought a microwave and started drying our slides in there, thought that that might be the problem but we did a comparison check on slides from the microwave and the drying oven.  Still the problem is here..... The problem seems to be with our GI biopsies and so know I am wondering is there something going on with the tissue processor?  Any help would be greatly appreciated......
