This is the most cautious approach, and for antibodies where there is no internal controls that would be your only way to verify that the studies worked. But it's also associated with some unnecessary rejection of good studies because controls aren't treated the same way as the patient slides.

Good approach and we do it on our "technical-only" cases where the slides are returned to the outside pathologists for interpretation.
