Abstract
BACKGROUND: We sought to compare the performance of the AdvanSure assay to the Hybrid Capture (HC) 2 for the detection of high-risk human papillomavirus (HR HPV). METHODS: A total of 855 cervical swab specimens were obtained. We submitted all specimens for HR HPV detection with HC2 and the AdvanSure assay. We subsequently analyzed discordant results and specimens that were positive on both assays using restriction fragment mass polymorphism (RFMP) genotyping analysis. RESULTS: HC2 yielded positive results in 12.0% of specimens, while the AdvanSure assay detected one of 13 HR HPV types in 11.5% of specimens. The overall agreement rate between the assays was 98.5% with a kappa coefficient of 0.928. Discordant results between these two assays were observed in 12 cases, seven were positive only on HC2 and five were positive only on AdvanSure. RFMP analysis of the 12 discordant cases revealed three false-positive results using HC2, and one false-positive and five false-negative results using AdvanSure. CONCLUSIONS: Considering the high agreement rate with HC2 and the ability to differentiate 35 HPV genotypes including HPV 16/18, the AdvanSure assay could be used as a laboratory testing method for HPV infection screening.
