Background: Human papillomavirus (HPV) detection based on cervical cytology specimens is useful for cervical cancer screening. The aim of this study was to compare Mojin HPV kit (a newly developed HPV genotyping assay) with the Cobas 4800 HPV test in detecting high-risk (HR) HPV.
Methods: A total of 347 cervical exfoliated cell specimens were tested using the Mojin HPV kit and Cobas 4800 HPV test. When the results from the two tests were inconsistent, gene sequencing was performed for correction.
Results: For HR-HPV, the results of the two assays agreed by 96.3% [Kappa = 0.911; 95% confidence interval (CI): 0.863 - 0.958)]. The positive and negative coincidence rates between the two tests were 96.0% (95% CI: 92.7% - 98.0%) and 97.0% (95% CI: 91.5% - 99.4%), respectively. Of the 13 samples with discordant results, 3 samples were false positive and 10 samples were true negative for Mojin HPV test, according to the identification by sequencing. For HPV16 genotyping, the total coincidence rate between the 2 tests was 100% (Kappa = 1.000), and 99.7% (Kappa = 0.973; 95% CI: 0.905 - 1.000) for HPV18.
Conclusions: Mojin HPV kit may be as effective as Cobas 4800 HPV assay in detecting the total HR-HPV, especially HPV16 or HPV18.
