A key parameter for the continued success of cervical cancer screening is quality-controlled use of human papillomavirus (HPV) tests that are clinically validated according to international guidelines. The clinical accuracy for cervical screening of the Allplex HPV HR Detection (Allplex), which concurrently detects and distinguishes 12 high-risk HPV types (16,18,31,33,35,39,45,51,52,56,58,59) and HPV66 and HPV68 was assessed on SurePath samples by comparing its performance to the second-generation comparator BD Onclarity HPV assay (Onclarity). The absolute clinical sensitivity, assessed on 76 samples derived from a screening population with underlying CIN2+, of Allplex and Onclarity was 98.7 % (95 % CI, 92.9–100.0 %) and 100.0 % (95 % CI, 95.2–100.0 %), respectively, with relative sensitivity of Allplex of 0.99 (95 % CI; 0.96–1.01). The absolute clinical specificity, assessed on 801 consecutive clinician-collected cervical samples obtained from women 30 to 59 years old attending the routine Danish cervical screening program, for Allplex and Onclarity was 92.5 % (95 % CI, 90.4–94.2 %) and 92.5 % (95 % CI, 90.4–94.2 %), respectively, with relative specificity of Allplex of 1.00 (95 % CI; 0.99–1.01). With thresholds mandated by international guidelines of ≥90 % for relative clinical sensitivity (p = 0.001) and ≥98 % for relative clinical specificity (p = 0.0018), Allplex was non-inferior to Onclarity. Excellent intra- and inter-laboratory agreement of Allplex was observed, both overall (99.2 % and 99.6 %) and at the genotype level (range: 99.6–100.0 %). By fulfilling all guideline requirements for clinical sensitivity, specificity, and reproducibility, Allplex can be considered clinically validated for primary cervical screening using clinician-collected SurePath samples. With this study, Allplex also meets the criteria for a second-generation HPV comparator test.
