Bacterial culture of apheresis platelets: a mathematical model of the residual rate of contamination based on unconfirmed positive results

Abstract

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.
