Abstract To understand the current status and variation trend of syphilis serological testing in laboratories of national free pre-pregnancy health examination in Jiangsu province from 2015 to 2020. Methods: The external quality assessment of syphilis serology testing was organized twice a year in laboratories of national free pre-pregnancy health examination in Jiangsu province, and the samples were detected and the test results were reported within the required time．Subsequently, all these test results were statistically analyzed by Health Development Research Center of Jiangsu. Results: From 2015 to 2020, the total qualification rate of external quality assessment of syphilis serology testing was stabled at more than 96%. The main method of syphilis serology testing was specific test, and the rate of the specific test increased year by year in all these laboratories. The coincidence rates of specific test and non-specific test increased from 97.70% and 89.09% to 100.00%, while the rate of positive results missed detection decreased from 3.65% and 27.27% to 0.00%, respectively. Conclusion: From 2015 to 2020, the coincidence rates of syphilis serological testing in laboratories of national free pre-pregnancy health examination in Jiangsu province increased to varying degrees, the rate of positive results missed detection decreased to varying degrees, and the overall detection capacity of syphilis serological testing had been improved.
