Greater than 99·5% of collections contain no viable, aerobic bacteria in solution at the time of early culture testing. For every confirmed positive contaminated collection detected, there are at most 19 collections with low concentrations of dormant bacteria that are not readily detected by early BacT/ALERT™ culture.

The safety initiative with new selection criteria for EBV led to decreased complications among donors 16 to 18 years old, such that the risk for 16-year-olds was no longer different from that observed for 19-year-olds in the analysis stratified by age, sex, and donation status.

The risk of TRALI after plasma transfusion has been markedly reduced for blood groups A, B, and O but not for AB, reflecting continued reliance on group AB plasma from female donors to meet increasing demand.
