Seegene Anyplex II assays detect HPV consistently using DNA extracts from different extraction methods.

Abstract

The efficiency of PCR-based diagnostic assays can be impacted by the quality of DNA template, and anal samples can be particularly problematic due to the presence of faecal contaminants. Here, we compared the Quick-DNA Viral Kit (Zymo, Zymo Research, CA) and MagNA Pure 96 DNA and Viral NA Small Volume Kit (MP96, Roche) for use of the Seegene Anyplex II HPV28 assay (Anyplex28, Seegene) with anal samples. A total of 94 anal samples extracted using the MP96 and Zymo kits were tested via the Anyplex28, which detects high-risk human papillomavirus (HR-HPV, Panel A) and low-risk (LR-HPV, Panel B) HPV types. Testing the HR-HPV types (Panel A), 86 (91.5%) MP96 and 84 (89.4%) Zymo samples were deemed assessable. Overall agreement between the two methods was 87/94 (92.6%, 95% CI: 85.3-97.0) with the Kappa value of 0.678 (0.5-0.9). Of the 87 assessable samples, 50 (57.5%) were concordant, 34 (39.1%) partially concordant, and 10 (11.5%)discordant. In conclusion, the Anyplex28 produces comparable HPV genotyping results when using DNA extracts from either of these two methods.
