Diagnostic value of an abnormal smear in non-pregnant women. Evaluation of positive smear from the surface of the portio obtained by the cottonswab method or by the dry wooden Ayre spatula and the relevance of positive smear from the endocervix and/or from the surface of the portio.

During a 3-4 year period, 324 women with a positive smear were registered consecutively and prospectively and divided into two groups according to the design of the investigation. In one group the smear was taken with an Ayre spatula and in the other group with a cotton swab. The purpose of this investigation has been to make a comparison between the endocervical smear and the smear taken from the surface of the portio and at the same time between the samples taken with a dry wooden Ayre spatula and with a cotton swab. No differences were found. The cytological findings have been registered and correlated both with the histological findings by colposcopically directed punch-biopsies and endocervical curettings and with the final histological diagnosis obtained by punch-biopsy, conization or hysterectomy.
