The purpose of look-back is to locate and quarantine current and previously donated units from a donor who tests positive for either hepatitis C virus or HIV-1 and to notify the recipients of units that have been transfused.Because test methods have become more sensitive,viral contaminants in prior donations may not have been detected and the process of look-back avoids additional cases of viral transmission.
