Microbes and blood transfusion.

Abstract

Transfusion medicine has been constantly evolving through the years with improved technologies that enhance the capability of identifying existing and newer emerging transfusion transmissible infections (TTI). In spite of the efforts made by blood banks the risk of TTI remains. This article deals with the various steps involved in ensuring blood safety, i.e. donor selection, role of screening donated blood for known and emerging infections, issues and assessment of threat posed by the risk, methodologies employed for testing and possible suggestions to improve transfusion services. While the threat of TTI remains, with a concerted effort of private and government organisations, and co-operation from the diagnostic companies, it is possible to raise the levels of blood safety. A surveillance system is also essential to identify any new agents that might pose a threat in a geographic area and to include them too in the screening process.
