Abstract: 【Objective】 To estimate the seroprevalence of SARS-CoV-2 infection among blood donors during the COVID-19 outbreak, in order to provide reference for formulating coping strategies. 【Methods】 A total of 3 623 samples of healthy blood donors in Xi′an from January 1 to June 14, 2020 were collected and tested by chemiluminescence microparticle immunoassays(CMIA). The correlation between the number of confirmed cases of COVID-19 in Xi′an and the monthly prevalence trend of SARS-CoV-2 antibody in Xi′an was also studied. 【Results】 Among the 3 623 blood donors, 3 were reactive by CMIA, with the seroprevalence rate of SARS-CoV-2 at 0.083%(95%CI: 0.00, 0.18). The earliest yielding of SARS-CoV-2 in Xi′an was in February 4, 2020. 【Conclusion】 The SARS-CoV-2 seroprevalence rate in Xi′an is low, which is in line with the local prevalence status. It is suggested that serological detection of blood donors is a way to monitor the prevalence of COVID-19.
