We have performed a retrospective analysis of 126 608 smears submitted to our laboratory by general practitioners and family planning clinics.2 We compared the rate of detection of cytological abnormalities associated with the three most popular devices: the spatula alone (predominantly Aylesbury spatulas), the Cervex brush, and a combination of a spatula and brush. Table 1 shows the results (presented with the permission of the editor of Cytopathology). The results obtained with the Cervex brush were different from those obtained with the other techniques: the brush produced a higher proportion of satisfactory smears but a lower rate of diagnosis of cytological abnormality.
