Objectives: The aim of this study is to evaluate the utility of the APTIMA assay, which identifies E6/E7 mRNA of 14 types of high-risk human papillomavirus (HR-HPV), for the diagnosis of grade 2 or higher cervical intraepithelial neoplasia (CIN), and to compare the sensitivity of this test with other diagnostic tests. Methods: A total of 203 patients, referred for a colposcopy due to an abnormal cytology or a positive test for HR-HPV, were evaluated with the APTIMA, Hybrid Capture (HC2), cobas 4800, Linear Array and p16INK4a immunohistochemical staining assays. Results: Sensitivity was calculated for all the tests, using CIN2+ and CIN3+ as endpoints, with sensitivity values above 90% observed for all the diagnostic tests. The sensitivity for APTIMA was 92.80% and 92.94% for CIN2+ and CIN3+ respectively (p<0.0001), for HC2 96.80% and 95.29% (p<0.0001), for cobas 4800 96.00% and 95.29% (p=0.011), for Linear Array 98.40% and 97.65% (p=0.007) and for p16INK4a immunohistochemical staining 95.90% and 96.39% (p<0.0001). The APTIMA assay and the p16INK4a immunohistochemical staining had the best specificity values, 35.90% and 47.94% respectively (p<0.0001). Conclusion: APTIMA has a sensitivity similar to that of other diagnostic tests for the detection of CIN2+, which is why it could be a useful test for cervical cancer
