Quality Monitoring of Blood Components

Blood establishments manufacture blood components to meet agreed specifications.[1,2,3] However, because of biological variation of the starting material (i.e. the donor), not all components produced can be expected to meet specification. Quality monitoring is therefore performed on a proportion of components (usually 1% of components of which a large number are made; 10 per day when small numbers are made) to assess conformance. For some parameters, e.g. LD performance, statistical process monitoring is used to detect any drift in process capability before overt failures to specification are found.
