Abstract
An automatic screening apparatus that screens all pap smear slides called normal by cytotechnologist. These normal pap smears will contain the mistakes, false negatives, which must be recovered as a measure of the cytotechnologist's performance. Additionally, these mistakes must be discovered to improve the quality of the laboratory services. The automated screening machine after rescreening the normals, rank orders of the pap smears with those "normals" most likely to be missed ranked at the top. Another human screener re-examines those pap smears with high ranking to determine if the first human screener misclassified the pap smear. Mistakes are recovered and the performance of the first screener is assessed. Proficiency testing is accomplished with 100% quality control.
