HCV Detection among Blood Donors from 18 Provincial Blood Centers in China from 2018 to 2022
Objective The data of hepatitis C virus(HCV)among blood donors in the service areas of provincial blood centers were analyzed.Methods Anti-HCV and HCV RNA data from 2018 to 2022 from first-time and repeat donors at 18 provincial blood HCV ELISA and anti-HCV ELISA negative RNA was analyzed.These was related to the year,blood center,and first-time and repeat donors.Results Between 2018 and 2022,the total unqualified rate of HCV decreased from 26.61/10 000 to 15.17/10 000(χ2=717.71,P＜0.01).The highest rate was 25.72/10 000 in western China and the lowest rate was 11.96/10 000 in eastern China.The unqualified rate of anti-HCV ELISA in first-time blood donors(30.50/10 000)was higher than that in repeat blood donors(7.42/10 000).The unqualified rate of anti-HCV ELISA negative HCV-RNA in each blood center ranged from 0 to 7.54/10 000.Conclusion The unqualified rate of HCV among blood donors in 18 centers decreased year by year.There are significant regional characteristics in the unqualified rate of HCV detection.Compared with the first-time blood donors,repeat donors were a lower-risk group.HCV RNA testing played an important role in blood safety.
