Since the method is qualitative, all you can do is provide proof that
your controls are good. This can be done by "certifying" your controls
in-house (and, if possible, by a reference lab - which could be the next
hospital or lab down the road). Keep records of control verification,
use, performance and reliability. This can all be written in a
procedure. Part of that should tell what to do when a control does not
work.

Subject: Immuno procedure for method performance specifications
To: Histonet@pathology.swmed.edu

During our CAP inspection the inspector recommended we develop a
procedure for
method performance specifications for Anatomic pathology especially in
Immunohistochemistry. We argued that our immuno's were all interpretive.
Has
anyone else been sited for this in AP or have a procedure for
Immunohistochemistry already?

CAP Question was Lab General 1.4202, 1.4203, 1.4208, 1.4210, 1.4210,
1.4216
