Reporting adverse events

An adverse reaction or event is an undesirable response or effect in a patient, temporally associated with the administration of blood or blood component

Hospitals must report adverse events as soon as possible to:

  • NHSBT (NHS Blood and Transplant - refer to the information in this section)

  • Medicines and Healthcare Products Regulatory Agency's (MHRA) system for Serious Adverse Blood Reactions and Events (SABRE) 
    You will need to register with SABRE before you can report. SABRE does not replace your local reporting arrangements.
