Abstract
To compare the most commonly used cervical sampling devices. We examined seven cytology sampling devices (Cytobrush, Cervex brush, Szalay spatula, Papex spatula, WrGKK spatula [main social security agency in Vienna], cotton swab and loop). Eight hundred smears were assessed for even distribution of cells, percentage of slide surface covered with cells, and presence and number of endocervical cells. Even distribution of cells was best with the WrGKK spatula. Percentage of slide surface covered with evaluable cells was best with the Cytobrush. Highest ranking for the presence of endocervical cells was found for the Cytobrush. Cotton swabs and loop showed inferior results in all categories. The use of cervical cell sampling devices showing the best cytologic results improves the interpretation and validity of cervical smears. Our results suggest that cotton swabs and loops should not be used for cervical cell sampling.
