The rate of reporting endocervical cells in the Papanicolaou smears of 579 women with a past history of cervical biopsy was compared with an age matched control group of women. During a time period when only spatulae (Ayre Lerner and Aylesbury) were used for sampling, 55% of the cases and 53% of the controls had the presence of endocervical cells reported. When cytobrushes as well as spatulae were used, the proportion rose to 70% for cases and 73% for controls. We conclude that the probability of endocervical cells being reported is not influenced by a past history of cervical biopsy, but is substantially improved if a combination of cytobrush and spatula is provided for sampling.
