Additional file 1: Table S1. of Quality assurance of human papillomavirus (HPV) testing in the implementation of HPV primary screening in Norway: an inter-laboratory reproducibility study

Ct-values for HPV and beta-globin detection in samples with discordant results. The Ct-values of the discordant samples were generally above 38.4 (with two exceptions), and hence close to the clinical Ct cut-off values. The Ct-values of beta-globin were for all samples between 25.5 and 28, indicating sufficient quality of the input DNA. (DOCX 18 kb)
