[Histonet] IHC Validation

[Arrington, Karla A]

I am validating IHC's. What is the CAP requirements regarding negative slides. I've asked CAP but have not received a response. 
Are 10 negative patient tissues ran for each antibody using the negative protocol or are they ran using each antibody but also a known 
Negative control ran using the negative protocol? 
Thanks!
