Abstract Hepatitis B virus HBV is prevalent in China and screening of blood donors is mandatory. Up to now ELISA has been universally used by the China blood bank. However this strategy has sometimes failed due to the high frequency of nucleoside acid mutations. Understanding HBV evolution and strain diversity could help devise a better screening
