【Objective】 To investigate the prevalence of hepatitis E virus (HEV) among voluntary blood donors, and the viability and practicability of nucleic acid testing (NAT) in Jinhua area. 【Methods】 Blood samples from 1 017 voluntary blood donors at Jinhua Blood Center from April to May 2021 were collected, and HEV RNA was detected by CHURAS BSS1200 blood nucleic acid detection system. The reactive samples were re-tested for IgM and IgG antibodies by ELISA, and HEV genotyping by gene sequencing. 【Results】 The yield rate of HEV RNA out of voluntary blood donors in Jinhua was 0.98 ‰ (1 / 017). The individual was negative for IgM and IgG antibodies, but was confirmed to be HEV RNA genotype 4 by sequencing. 【Conclusion】 HEV RNA positive donors have been found in this study. HEV RNA blood screening can effectively enhance the safety of blood transfusion.
