The quality of the Pap smear

Three methods of cervical Pap smear have been studied: the classical spatula, the combination of spatula and cytobrush, and the Cervex-Brush. Thirty-two percent of the spatula smears did not provide endocervical cylinder cells. Significantly better results can be achieved by performing the smear with a combination of spatula and cytobrush (11% without cylinder cells), or with Cervex-Brush (15% without cylinder cells). Cervical smears using a spatula alone are therefore discouraged.
