Objective: Identify the spatula that achieves the lowest percentage of "less tan optimal" PAP smears.Methodology: Cross-sectional study, with an intentional and proportionally stratified simple, consisting of 761 women between 25 and 64 years of age, in the public health centers of the Northern Metropolitan Health Service. Midwives took the PAP sample from each women using one of the three spatulas: Ayre, a plastic spatula and the combination Citobrush-Ayre (C+A). (Fig 1, 2, 3).

This result was statistically significant (pvalue
