[Histonet] nuclear haziness

[Jean Brinker]

We are having an issue with nuclear haziness on prostate biopsies in our small 
urology laboratory.  It occurs randomly, appearing on some levels and not others 
within the same block. Another scenario is that we sometimes see it occur only 
in one small area of a core and the remaining tissue in the core looks 
beautiful. It can occur throughout a case (12 blocks) or not at all. We have 
checked for obvious problems, i.e. reagent contamination on the processor and 
stainer, ruled out temperature issues, microtome problems, etc. to no avail. I 
would appreciate any input/suggestions that would help to alleviate this 
problem. 

Thank you,
