Cytologic Features of Low-Grade Squamous Intraepithelial Lesion in ThinPrep Papanicolaou Test Slides and Conventional Smears: Comparison of Cases That Performed Poorly With Those That Performed Well in the College of American Pathologists Interlaboratory Comparison Program in Cervicovaginal Cytology

Abstract

ThinPrep Pap Test cases and conventional smears with a diagnosis of low-grade squamous intraepithelial lesion that perform poorly in this program have significantly fewer abnormal cells than those that perform well. The median number of abnormal cells in cases that performed well is lower than that of comparable high-grade cases in the program.
