    Objectives: Correlate the detection of human Papillomavirus, by the method of Hybrid Capture, with the Atypia of Undetermined Significance. Among those with positive result for human Papillomavirus, define the groups found (Papillomavirus types of low and high risk) and their viral loads. Methods: This is an observational, cross-sectional and analytical study, which were entered into a database the results of cytology exams and Hybrid Capture of 474 patients from routine of cytology laboratory and Hybrid Capture of Associação Fundo Incentivo a Pesquisa (AFIP), from January 2012 to December 2013. These tests have been conducted and issued their reports. The age of patients ranged from 15 to 75 years, with an average of 33 years and 8 months. Were included diagnoses of patients who had cytological and molecular tests (CH II) in addition, positive cervical smears for Atypia of undetermined significance - ASC-US and ASC-H. Results: This study showed that 60.8% of ASC were positive in Hybrid Capture, being 58.6% for ASC-US and 83.3% for ASC-H. Regardless of the ASC subgroup, the high-risk virus was most commonly found (87.8%), either alone or associated with low-risk HPV (54.8% and 33% respectively). ASC-US demonstrated a tendency to lower viral loads, whereas ASC-H at higher viral loads. Conclusion: The method of Hybrid Capture II applied to Atypia of Undetermined Significance resulted in a positivity rate of 58.6% for ASC-US, and 83.3% for ASC-H. Regarding ASC-US, there were types "high" and "low and high risk" (53.4% and 33.2%, respectively) with low viral loads and intermediate. As the ASC-H, there were types "high" and "low and high risk" (65.8% and 31.4%, respectively) with high viral loads. Thus, in Atypia of Undetermined Significance, regardless of the subgroup, the high-risk virus was the most commonly found type, either alone or associated with low-risk HPV, and viral loads tended to rise according the severity of the atypia found in cytology.
