The sensitivity of cervical culture, cervi-cal swab PCR and SOLVS PCR were 75.8% (25/33),87.9% (29/33) and 97.0% (32/33), respectively. Thespecificities of the respective methods were 100%(265/265), 99.6% (264/265) and 99.6% (264/265).The positive predictive values (PPVs) of the respectivemethods were 100% (25/25), 96.7% (29/30) and97.0% (32/33). The negative predictive values (NPVs)of the respective methods were 97.1% (265/273),98.5% (264/268) and 99.6% (264/265).Conclusions: The performance of SOLVS PCR is atleast as good as that of conventional cervical PCR tech-niques for the detection of NG. SOLVS may take theplace of cervical swabs for screening of NG infectionin women by PCR.展开更多
