[Histonet] Negative controls for special stains (non-organism)?!?!

[Morken, Tim]

Hi all,

Our Joint Commission audit was just completed (first time for JC for me). We passed almost everything fine.

The one thing they came up with is that we don't use "negative controls" for most of the special stains - like trichrome, congo red, etc. We use negative controls for micro-organism cases but not for the others. In fact I've never heard of anyone doing that.

Has anyone had this issue with JC? Does anyone run "negative" controls for non-organism special stains? Frankly I'm not sure how that would be done for something like a trichrome or other purely tissue-element stains.

Thanks for any insight!
