ABSTRACT
Introduction: Only in some Latin American countries the cervical cancer screening programs have been successful, in comparison with the outcome in developed countries. One difference should be due the lack of quality control mechanisms in the cytology laboratories.
Objective: The objective of this paper is to evaluate the achievement of two quality control mechanisms and make a comparison between them : the common quality control procedure against the rapid rescreening procedure.
Material and methods: This is a retrospective study of concordance of the cytological diagnosis with the histopathologic results in all the positive cases along one year.
Results: Both procedures showed similar findings evaluated by diagnostic concordance and kappa index.
Conclusions: The conclusion is that both quality control mechanisms to evaluate the assurance of the cytologic diagnosis in the Cytopathology Laboratory of the General Hospital of Mexico have acceptable results.
