A retrospective review of all women who were referred for colposcopy because of a moderate dyskaryotic smear was carried out for a 6-month period. Data collected included colposcopic impression, procedure performed and final histopathology. Two cytologists who were unaware of the original smear report were asked to reclassify these smears using the new 2-tier system. Their findings were compared with the documented colposcopic and histopathology results.
