Prospective and Retrospective Review of Gynecologic Cytopathology: Findings From the College of American Pathologists Gynecologic Cytopathology Quality Consensus Conference Working Group 2

Context.—Two quality metrics for gynecologic cytology are the subject of this review: “prospective rescreening” and “retrospective rescreening.” Objective.—To offer consensus best practice approaches based on the College of American Pathologists' laboratory-based survey funded by the Centers for Disease Control and Prevention.
