Increased utilization, verification, and clinical implications of immunocytochemistry: Experience in a northern New England hospital.

Utilization of ICC at our institution has increased dramatically in recent years. Our verification process confirmed reliability in the majority of antibodies, but did identify several inconsistent antibodies. Although, in our series, no adverse clinical outcomes resulted from preverification use of these inconsistent antibodies, we encourage other institutions to confirm reliability of antibodies prior to use for diagnostic ICC.
