Predicting improvement in detection of bacteria in apheresis platelets by maintaining constant component sampling proportion.

abstract：BACKGROUND:To facilitate volume control in neonates, platelets (PLTs) are aliquoted and stored for short periods in non-gas-permeable syringes before infusion. Although agitation of PLTs during storage in gas-permeable bags is performed to maintain their quality, the effect of syringe agitation during storage is unknow...
