Quality control and transfusion reactions.

The relative safety of homologous blood transfusion is in large part due to constant surveillance by blood bankers and clinicians. Quality control of blood supply and transfusion includes collection, documentation, storage, serological testing, administration and follow-up. The provision of serologically compatible blood requires meticulous monitoring of grouping, screening and crossmatching techniques. A hospital transfusion committee should be an integral part of any quality control programme to ensure effective communication between clinical, laboratory and administrative staff.
