Background: Transfusion of freshly collected blood products (FCBP) is sometimes necessary to save service member (SM) lives in austere deployed environments.

In austere deployment environments, transfusion of freshly collected blood products from volunteer donors is sometimes necessary to save wounded service members' lives. Because these blood products may have an increased risk of transmitting bloodborne pathogens, recipients are administratively tracked and offered serial serologic testing by the Blood Look Back (BLB) program. This study evaluates the frequency of transfusion-transmissible infections (TTIs) in U.
