      We determined the limit of detection of the RealStar HEV RT-PCR V2.0 Kit (altona Diagnostics, RS) utilizing 3 RNA extraction methods (COBAS® AmpliPrep Total Nucleic Acid Isolation Kit, TNAi Roche; MagNA Pure 96 DNA, Viral NA SV Kit, MgP; QIAamp Viral RNA mini Kit Qiagen; VRK) in plasma and stool. The most sensitive method was evaluated in a total of 307 longitudinal samples of patients with HEV infection (acute = 18/chronic = 36) and compared to results with the former diagnostic standard of our centre (TNAi/FastTrack Diagnostic; FTD).
