“…6 HPV L1 consensus primers MY09, MY11, and HMB01 and β-globin primers PC04 and GH2 were used to simultaneously amplify HPV DNA and β-globin. Samples that were HPV positive by generic probe or β-globin negative were typed with the Roche Linear Array HPV genotyping test (Roche Molecular Systems, Inc, Alameda, CA) for 37 HPV types, including 21 clinically relevant types: HPV types 6 and 11 (due to their association with genital warts 9,10 ) and 19 oncogenic types classified as carcinogenic, probably carcinogenic, or possibly carcinogenic: 16,18,26,31,33,35,39,45,51,52,53,56,58,59,66,68,73,82,IS39 11,12 Samples that were β-globin negative during the initial dot blot step and HPV negative by the Roche assay were considered insufficient.…”
