[Methods ] Two thousand one hundred and six women undergoing cervical cytological examination in Zhuhai Family Planning Service Center during Jan. 7 to Dec. 9 were enrolled in the study. Every sample was detected by both DNA-ICM and conventional cytology. Biopsy was taken if positive result was found and pathology of colposcopic biopsy was considered as golden standard. The relative sensitivity relative specificity positive predictive value (PPV) and negative predictive value (NPV) of DNA-ICM conventional cytology and combining both of them were calculated. [Results ] Two thousand and eighty-three samples were satisfactory. Of the cases recommended for biopsy had pathological diagnosis and follow-up. Relative sensitivity and relative specificity were 8.% and 99.9% of DNA-ICM; 7.% and 99.% of coventional cytology; 9.7% and 99.% combination of the two tests respectively. [Conclusion] Being compared with conventional cytology DNA-ICM has the higher sensitivity on detection of the cervical cancer and pre-cancerous lesions with no less specificity. If DNA-ICM was combined with conventional cytology the sensitivity of the test will be improved.
