 - with covered probe positive for HPV Statistical unit: each procedure surveyed Viral assays HPV DNA detection will be performed on all samples keyboard, bare and covered probe using the cobas HPV Test Kit Roche: This test allows to detect the presence of cellular DNA and DNA of 14 high-risk HPV genotypes 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66 and 68 and to specifically identify the presence of HPV16 and 18. In case of positive result for both bare and covered probe, a detection of HPV complete episomal genome will be performed, and circular HPV DNA will be amplified using a polymerase whch selectively amplifies circular double-stranded DNA with specific degenerate HPV primers. The amplicons will then be sequenced using specific HPV primers GP5 GP6 MARINCEVIC Y-Zuniga et al, 2012, Virology.
