The LMNX genotyping kit HPV GP (LMNX) is based on the clinically validated GP5+/6+ PCR, with a genotyping readout as an alternative for the more established enzyme immunoassay (EIA) detection of 14 targeted high-risk human papillomavirus (HPV) types. LMNX is additionally provided with an internal control probe. Here, we present an analysis of the clinical performance of the LMNX using a sample panel and infrastructure provided by the international VALGENT (Validation of Genotyping Tests) project. This panel consisted of cervical specimens from approximately 1,000 women attending routine screening, “enriched” with 300 women with abnormal cytology. Cases were defined as women classified with cervical intraepithelial neoplasia (CIN) grade 2+ (CIN2+) (n = 102) or CIN3+ (n = 55) within the previous 18 months. Controls were women who had normal cytology results over two subsequent screening rounds at a 3-year interval (n = 746). The GP5+/6+-PCR EIA (EIA) was used as a comparator assay and showed sensitivities of 94.1% and 98.2% for CIN2+ and CIN3+, respectively, with a clinical specificity of 92.4% among women aged ≥30 years. The LMNX demonstrated clinical sensitivities of 96.1% for CIN2+ and of 98.2% for CIN3+ and a clinical specificity of 92.6% for women aged ≥30 years. The LMNX and EIA were in high agreement (Cohen's kappa = 0.969) for the detection of 14 hrHPVs in aggregate, and no significant difference was observed (McNemar's P = 0.629). The LMNX internal control detected 0.6% inadequate specimens. Based on our study results, we consider the LMNX, similarly to the EIA, useful for HPV-based cervical cancer screening.
