In recent years, several new cervical sampling techniques have been introduced to try to improve the accuracy of the cervical smear. In the present study four such techniques were compared: the Aylesbury spatula, Rolon spatula, Cervex device and Aylesbury spatula used in conjunction with a Cytobrush. The total number of smears collected was 14,172, 80% of which were from women under age 35. Despite large differences between the techniques with regard to the presence of endocervical cells in smears, no differences were found in the detection of dysplasia. Endocervical cells were seen significantly more often in dysplastic smears than in negative smears. There was little difference in the rate of unsatisfactory samples. It appears that in a young population, the instruments used for cervical sampling are not likely to significantly influence the detection of dysplasia if skilled personnel take the smears.
