Digene HC II test was used to identify HR- and/or low-risk (LR-)HPV infections in cervical swabs of 275 women attending our clinic for routine cytological screening and/or colposcopy because of an abnormal Pap smear comprising low-grade squamous intraepithelial lesions (LGSIL) and high-grade SIL (HGSIL).
Primary screening with HC2 generally detects 23% (95% confidence interval, CI: 13-23%) more CIN-2, CIN-3, or cancer compared to cytology at cut-off atypical squamous cells of undetermined significance (ASCUS) or LSIL, but is 6% (95% CI: 4-8%) less specific.
Primary screening with Hybrid Capture((R)) 2 (HC2) generally detects more than 90% of all CIN2, CIN3 or cancer cases, and is 25% (95% CI): 15-36%) relatively more sensitive than cytology at a cut-off of abnormal squamous cells of undetermined significance (ASC-US) (or low-grade squamous intraepithelial lesions (LSIL) if ASC-US unavailable), but is 6% (95% CI: 4-7%) relatively less specific.
