Abstract：Objective To understand the HIV positive conversion rate in blood donors with uncertain HIV antibody, and to explore the necessity of timely return visits among them. Methods We analyzed the information about return visits and testing of blood donors with uncertain HIV antibody in Changsha City, and surveyed their general condition, compliance, HIV positive conversion rate and time spent on positive conversion. Results A total of 81 blood donors with uncertain HIV antibody were screened in Changsha City from 2012 to 2020. Return visits were conducted among 31 blood donors with uncertain HIV antibody detected in 2016-2020, and the compliance rate of blood donors with uncertain HIV antibody was 35.5%, with the HIV positive conversion rate of 29.6%. Return visits did not affect the HIV positive conversion rate (χ2=0.009,P=0.926). As for the time spent on positive conversion, it took 2.0 (1.5, 9.5) months for blood donors with uncertain HIV antibody as well as return visits, which was much lower than the 19.0 (6.0, 35.0) months for those without return visits (Z=-2.334,P=0.018). Conclusion Return visits are conducive to the early detection of infection of blood donors with uncertain HIV antibody. Hence, it is necessary to make return visits to blood donors with uncertain HIV antibody in a timely manner.
