More efficient target capture chemistry in the new TMA assay version significantly improved sensitivity and diminished variability in detecting HBV strains of various genotypes. We recommend a triplicate ID-NAT repeat test strategy to eliminate discriminatory tests on false-non-repeat-reactive (anti-HBc-nonreactive) donations.

The current results indicate a high level of HEV endemicity throughout Poland compared with other countries. There is an urgent need to consider the protection of recipients of blood components against transfusion-transmitted HEV infection.
