Bacteria levels in components prepared from deliberately inoculated whole blood held for 8 or 24 hours at 20 to 24 degrees C

BACKGROUND: An increase from 8 to 24 hours in the time that units of whole blood can be held at room temperature after phlebotomy would give blood centers more flexibility in component manufacturing and might allow receipt of many infectious disease test results prior to component preparation. However, the potential for bacterial growth during prolonged holding periods requires further study.
