Comparison of real-time PCR and antigen assays for detection of hepatitis E virus in blood donors.

ABSTRACT: Hepatitis E virus (HEV) infection is recognized as an emerging and often undiagnosed disease in industrialized countries, with asymptomatic infections actually occurring in blood donors. Sensitive detection of HEV-RNA is crucial for diagnosis and monitoring of disease progression. We evaluated the analytical sensitivity and performance of three HEV RT-PCR assays (RealStar HEV reverse transcription-PCR [RT-PCR], hepatitis@ceeramTools, and ampliCube HEV RT-PCR) for screening of individuals for HEV infections (ID-nucleic acid amplification technology [ID-NAT]) and for blood donor pool screening (minipool-NAT [MP-NAT]). RNA was extracted using NucliSens easyMAG (ID-NAT) and a high-volume extraction protocol (4.8 ml, chemagic Viral 5K, MP-NAT). Three NAT assays were evaluated for ID-NAT but onl
