We recently had a CAP inspection for our small AP only lab. We do not do IHC, only special stains (DQ, PAS, iron, etc). We were cited a phase 2 deficiency for not doing proficiency testing on our special stains. I was incredulous. We discussed the criteria for "alternative performance assessment" and I am at a loss as to how our QC does not suffice in meeting this criteria. I've been doing these inspections (inspected and inspectING) for 15 years, and have never seen PT for special stains come up once. Is this new? CAP has been about as useful as an ear on my elbow in educating me on this. anyone else have this experience? any insights anyone can offer?
