Efficacy of the cytobrush versus the cotton swab in the collection of endocervical cells.
Cervical smears should contain endocervical cells to be accepted as adequate for a cytologic diagnosis. Before this study was undertaken, one-third of the smears received in the Cytology Laboratory of Odense University Hospital were inadequate. In an attempt to increase the rate of adequate smears, a randomized study was undertaken to compare the efficacy of the combined spatula-Cytobrush method to that of the spatula-cotton swab method traditionally used by doctors in Denmark. The incidence of smears containing cylindrical and/or metaplastic cells was 89% by the spatula-Cytobrush method as compared to 62% by the spatula-cotton swab method (P less than .001). There were large differences between the rates of adequate smears from the various doctors when using the spatula-cotton swab method (range, 14% to 82%); these differences were far less when using the spatula-Cytobrush method (range, 75% to 100%). A large-scale application of the spatula-Cytobrush method should result in fewer repeat smears required and fewer false-negative smears.
