Comparison of human papillomavirus testing strategies for triage of women referred with low-grade cytological abnormalities

Triage with sensitive HPV testing assays can substantially reduce the number of unnecessary referrals in women with low grade cytology with virtually no loss of sensitivity. Even greater gains can be made if p16 and type 16 are used, but some cases of CIN2 will be missed. In both cases short term surveillance will be needed.
