In this lecture Dr. Susan L. Stramer, PhD, MS, presents a continuation of the evolution, impact, and future directions of nucleic acid testing (NAT) for blood donor safety. The focus of this lecture is NAT plus competing technologies directed towards Emerging Infectious Disease (EID) agents. She begins by highlighting the agents that will be discussed and their current and evolving mitigation strategies. Strategies include variations of selective testing using antibody methods, modifications of NAT depending on the agent’s epidemiology including seasonal testing, focused testing and pool sizes used, red cell parasites that require red cell lysis followed by NAT, NAT multiplexing for multiple agent detection; alternatives to NAT including leukoreduction for leukocyte-associated agents, and pathogen reduction. Discussed are the agents for which NAT has been evaluated worldwide including: hepatitis E virus (HEV), West Nile virus (WNV), Babesia, Plasmodium, parvovirus, human T-cell leukemia virus (HTLV), cytomegalovirus (CMV), and bacteria. Dr. Stramer then discusses the international use and the agent-specific expansion of NAT. Lastly, Dr. Stramer discusses the impact of pathogen reduction and potential for the streamlining of donation screening strategies leading to the eventual co-existence of pathogen reduction and NAT.
