ObjectiveTo validate the efficacy of Seeplex HPV4A ACE for the detection of high-risk (HR) human papillomavirus (HPV) and HPV 16 and/or HPV 18 genotypes as compared to the PCR method and the Cervista HPV assays in cervical swab samples.MethodsBesides liquid-based cytology, additional 97 cervical swab samples were collected for HPV genotyping by HPV4A ACE, Cervista HPV assays, and PCR method. To check the statistical differences, we also conducted the paired proportion test, Cohen's κ statistic, and a receiver operating characteristic curve.ResultsSeeplex HPV4A ACE and the Cervista HPV HR showed substantial agreement with PCR for detection of HR HPVs (88.3%, κ=0.767 and 81.7%, κ=0.636, respectively). Seeplex HPV4A ACE also showed substantial agreement with the Cervista HPV 16/18 test (89.5%, κ=0.628). Additionally, the sensitivity and specificity of Seeplex HPV4A ACE and Cervista HPV HR were 91.4% vs. 84.5% and 73.4%, vs. 72.7%, respectively, when those higher than low-grade squamous intraepithelial lesions were regarded as abnormalities. HPV genotyping for HPV 16/18 detected cervical intraepithelial neoplasias (CINs) better than HR HPV tests (66.7% vs. 24.6% by HPV4A ACE, 52.6% vs. 25.9% by Cervista HPV assays in CIN II or more, relatively).ConclusionSeeplex HPV4A ACE is an effective method as the PCR and the Cervista HPV assays for the detection of HR HPVs and for genotyping of HPV 16 and 18.
