Abstract

In 632 women visiting a family planning clinic, paired cervical smears were taken using a wooden spatula and a Cytobrush R. Of the spatula smears 7.8% were unreliable with too little or scanty material to allow a cytologic diagnosis (class 0); 17.7% of spatula smears were inadequate, lacking endocervical cells. Combined spatula/Cytobrush R cytology reduced these figures significantly; 4.3% unreliable smears and 3.2% inadequate specimens. Seventy-three (11.6%) of the smears revealed some abnormality, in most cases Papanicolaou class IIIA, suggestive of mild dysplasia. In 10 cases, dysplastic cells were found only in the Cytobrush R cytology. It is concluded that the Cytobrush R adds to the improvement of smear quality and the accuracy of routine cervical cytology obtained by relatively inexperienced smear takers.
