Triage of HPV-positive women in Norway using cytology, HPV16/18 genotyping and HPV persistence
In a Norwegian pilot, triage of high-risk human papillomavirus (hrHPV)-positive women with reflex cytology followed by hrHPV testing 12 months later, yielded 82% of women referred to colposcopy and 24% with CIN3+. A policy stratified by the presence of HPV16/18 would be more efficient (66% referred to colposcopy) at the expense of small losses in the detection of precancer.
