| Abstract: | A programme of blood donor screening for parvovirus B19 was conducted from January to May 1990. The main aim of the study was to identify a B19 positive donation that could be used as a source of viral antigen for diagnostic serology. Out of 24000 donors tested one was positive for B19 antigen by counter current immunoelectrophoresis and over 100 ml of undiluted B19 containing material was obtained. However, much of the positive donation was incorporated in a plasma pool of 28 donations. An acid dissociation technique was used to recover B19 antigen from immune complexes formed in the plasma pool. |
