 Background and Objectives

 Post -transfusion hepatitis B may occure if donors donate blood in the window period, in the early convalescence phase and period with very low levels of HBsAg in blood.

 Case

 In December 2003, a case as post- transfusion hepatitis B in a blood recipient was reported to IBTO.The patient had received 2 units of red blood cells.Trace back program was set up to find out the donors possible involvement in viral transmission.

 Conclusions

 Donors and recipients were not positive for HBsAg and Anti-HBc IgM so current or recent infection during last 6 months had to be excluded. This case report explains a successful trace back , and accurate well- maintained records.
