- Abstract
Recently, a clinical need for an improved human papilloma virus (HPV) test that covers a broad range of genotypes has emerged as a valuable primary screening tool for cervical lesions. The liquid bead microarray (LBMA) assay is a recently developed high-throughput platform covering a broad range of genotypes. Here, we compared the clinical performance of two recently developed LBMA assays, GeneFinderTM HPV Liquid Bead Microarray (GeneFinder) and CareGENETM HPV genotyping kit-O (CareGENE), in the Korean general population. A total of 3,148 cervical swabs were tested by the GeneFinder and CareGENE assays. Cases with discrepant results between the two assays were subjected to direct sequencing as a reference method for evaluating the performance of the two LBMA assays. Among all swabs tested, 12.6% showed HPV positivity, and the prevalent HPV genotypes were HPV53, 70, 16, 39, and 51, in that order. The concordance rates between the two assays for the detection of HPV and for genotyping were 96.6% (kappa = 0.836) and 94.5% (kappa = 0.779), respectively. The two LBMA assays showed comparable sensitivity and specificity for HPV detection (GeneFinder: sensitivity 94.4% and specificity 98.7%, CareGENE: sensitivity 89.8% and specificity 99.6%) and for genotyping (GeneFinder: sensitivity 91.0% and specificity 96.6%, CareGENE: sensitivity 90.2% and specificity 99.1%). This is the first demonstration that CareGENE has comparable clinical performance to GeneFinder, which has been established to show excellent performance for screening HPV in previous studies. Both LBMA platforms are thus considered to be valuable tools for HPV detection and genotyping to improve cervical screening in the general population.
