Abstract: Objective To systematically evaluate the qualified rate for the reentry of donors from 2013 to 2023 in China. Methods Retrieved cross-sectional studies on the eligibility rate of donor reentry in China published from January 2014 to August 2024 in Duxiu, CNKI, VIP, WanFang Data, SinoMed, PubMed, Web of Science, Embase, and Cochrane library. Two researchers independently conducted literature screening, data extractionand quality evaluation, with Stata18.0 software for meta-analysis. Results A total of 25 articles were included, with 10 693 donors participated the test of donor reentry and 6796 donors got through the test. The results of meta-analysis showed that the qualified rate of donor reentry in China from 2013 to 2023 was 63.5%[95%CI(59.3%,67.8%)],the response rate of donor reentry was 18.3% [95% CI (10.1%, 26.6%)], and the qualified rates of deferred donors who got through the requalification process in screening HBsAg, HCV, HIV and TP were 57.5% [95% CI (48.8%, 66.2%)], 62.1% [95% CI (55.0%, 69.2%)], 65.0% [95% CI (55.3%, 73.8%)] and 64.0% [95% CI (57.3%, 70.6%) respectively. The rate of reentry from the deferred donors was 57.2% [95% CI (49.5%, 64.8%)], and the percentage of donors who got through the blood tests was 91.7% [95% CI (86.7%, 96.7%)], including heterogeneity, with P<0.05. Conclusion The high qualified rate of donor reentry in China can provide some reference and suggestion for other blood institute to carry out the procedure for reentry of donors.
