Participants were given a questionnaire to collect information on gender and sociodemographic characteristics. Next, a genital tract secretion specimen (urethral swabs from men, vaginal or cervical swabs from women) was collected from each participant and sent to the Shenzhen Center for Chronic Disease Control (SCCDC) to detect NG by nucleic acid testing. The sample collections were performed according to the Guidelines for Laboratory Diagnosis of Sexually Transmitted Diseases of China. 19 This test result was regarded as the reference test to evaluate the accuracy of NG tests in clinics. After finishing the above procedures, the participant would continue their normal medical service. The clinic physicians then decided on whether or not to collect a second specimen and test for NG in clinics according to their typical diagnostic practices and experiences. Patients with a positive diagnosis of gonorrhoea (according to the second gonorrhoea test result) from the clinics were reported to CISDCP online within 6 or 12 h. The staff at SCCDC compared the original clinical records and reported case information in CISDCP to calculate the unreported rate at the end of the survey.
