Objectives To determine clinical utility of Onclarity human papillomavirus (HPV) assay for atypical squamous cells-undetermined significance (ASC-US) triage, and the value of HPV genotyping within ASC-US. Methods Women (n = 33,858; 21 years or older) had HPV testing using Onclarity and Hybrid Capture 2 (HC2). ASC-US individuals (n = 1,960, 5.8%) were referred to colposcopy. Results Of ASC-US, 39.1% were HPV positive by Onclarity; HPV 16 was the most prevalent genotype (7.4%). Cervical intraepithelial neoplasia grade 2 (CIN 2) and CIN 3+ prevalences were 4.4% and 2.2%, respectively. Onclarity had sensitivity for CIN 2+ (85.7%) and CIN 3+ (91.4%), and specificities for CIN 2+ (64.1%) and CIN 3+ (62.0%), similar to HC2. Risks for CIN 3+ were 16.1%, 2.8%, 2.5%, and 2.7% with HPV 16, 18, 45, and 11 other genotypes, respectively. Conclusions Onclarity is clinically validated for ASC-US triage. Through risk stratification, genotyping could help identify women at highest risk for CIN 3+. [ABSTRACT FROM AUTHOR]
