Human papillomavirus (HPV) testing is more sensitive and has higher negative predictive value (NPV) than the Pap test for the detection of cervical intraepithelial neoplasia (CIN) in patients with atypical squamous cells of undetermined significance (ASCUS) cytology, but has low specificity, leading to high referral rates to second-level triage. Our goal was to identify the prognostic significance of HPV viral load figures.We evaluated whether a correlation between viral load, expressed as relative light units/cutoff (RLU/CO), and the severity of cervical lesions existed in 614 ASCUS cases. Hybrid Capture 2 (HC2®) RLU/CO values, categorised into five classes, were correlated to clinical outcomes and statistically analysed. A significant correlation (p1,000 (p
