Abstract: | OBJECTIVE: To compare cervicovaginal smears obtained by a cotton-tipped swab with those obtained by cervix brush and modified Ayre spatula. STUDY DESIGN: A combined cervicovaginal smear was collected from 100 women using 3 different collection devices: cotton-tipped swab, cervix brush, and modified Ayre spatula. In each patient a set of 3 smears was collected by the same cytotechnologist using all 3 devices in random order. Smears were evaluated using parameters mandatory for an optimal smear: evenly dispersed, well-preserved, adequate cells from the transformation zone. The cost and availability of the collection devices were also considered. RESULTS: The swab was the most effective device in obtaining thin, evenly spread, adequate, well-preserved smears as against the cervix brush and Ayre spatula. The pickup of abnormal cells was similar with the cotton-tipped swab and cervix brush, while the Ayre spatula failed to yield high grade squamous intraepithelial lesions, atypical glandular cells of undetermined significance and adenocarcinoma cells. The cotton-tipped swab proved to be the most cost effective. CONCLUSION: A properly prepared cotton-tipped swab is an inexpensive, readily available, nontraumatic collection device that yields smear of optimal quality. |
