Reporting adverse events and reactions

NHSBT must be informed immediately of all adverse reactions and events.

Documented details should include:

  • the patient involved
  • the type of reaction or event
  • the reason for transfusion
  • the implicated component (including donation number)
  • the contact details of the clinical staff looking after the patient


A serious adverse reaction notification report must also be made as soon as possible via SABRE (Serious Adverse Blood Reactions and Events) to MHRA (Medicines and Healthcare Products Regulatory Agency) and SHOT (Serious Hazards of Transfusion).

Advice on clinical management and investigation of serious adverse reactions can be sought from the hospital consultant responsible for blood transfusion.

The NHSBT duty consultant for patients must be informed immediately of serious adverse reactions to transfusion that require investigation or involvement by NHSBT. This is particularly important in cases of suspected bacterial contamination because other components may need to be recalled. Contact your Hospital Services department for details of the duty consultant.

The request form (see the request forms page in this section) provides information on the minimum sample requirements.
