[Histonet] CAP and negative IHC controls

[Debra Siena]

It is my understanding that you still need a negative tissue control but if using a polymer detection kit that you may stop doing a negative reagent control.  The negative tissue control is a tissue known to not contain the antigen in the tissue, it can be an internal control, or a separate control but if internal control, then it must be designated as to how it will be used in your procedure manual.  Hope that helps.

How is everyone interpreting the CAP rule about using negative controls? Do we still need a negative with each patient slide?
