OBJECTIVE: The study examined interrelationships between sensitivity and specificity of "reflex human papillomavirus deoxyribonucleic acid testing" from liquid-based cervical cytologic specimens by means of receiver operator characteristics curves. STUDY DESIGN: A cohort study was performed on 265 women evaluated by colposcopy because of atypical squamous cells of undetermined significance or low-grade squamous intraepithelial lesion found on Papanicolaou smear. RESULTS: At a positive threshold of 0.2 pg/ml (1000 copies of human papillomavirus per test), human papillomavirus deoxyribonucleic acid testing detected 86% of women with cervical intraepithelial neoplasia and 93% of women with high-grade cervical intraepithelial neoplasia with a specificity of 30%. Decreasing the sensitivity of the human papillomavirus test to 1 pg/ml (5000 copies of human papillomavirus per test) improved the specificity of a positive result to 44% but decreased the clinical sensitivity to 78% for cervical intraepithelial neoplasia grade 2 or 3. Relationships between sensitivity and specificity were influenced by patient age and referral diagnosis. For example, limiting the analysis to only women with a referral for atypical squamous cells of undetermined significance found on Papanicolaou smear and a positive human papillomavirus test threshold of 0.5 pg/ml produced a sensitivity of 90% for cervical intraepithelial neoplasia grade 2 or 3 and a test specificity of 55%. CONCLUSION: Human papillomavirus deoxyribonucleic acid testing of residual cellular material from liquid cytologic specimens appears to be more appropriate for older women (>30 years old) and women with atypical squamous cells of undetermined significance, as opposed to low-grade squamous intraepithelial lesion, on their Papanicolaou smears.
