Blood Transfusion

There is a blood transfusion service provided at 7 laboratories across the Barts Health NHS Trust, Homerton Healthcare NHS Foundation Trust and Lewisham and Greenwich NHS Trust. The aspired ‘hub and spoke’ operating model is centred at The Royal London Hospital (RLH); a busy major trauma centre which hosts the London Air Ambulance and connects to essential service laboratories supporting various clinical specialities at our partnered hospital sites.  

The Blood transfusion service provides blood components to patients requiring transfusion support for a variety of conditions including sickle cell disease and thalassemia as well as surgical support for patients who have been involved in major traumas. The blood transfusion laboratories provide a service 24 hours a day, seven days a week, with Blood Transfusion consultant staff available to provide clinical support as required.

Biomedical scientists in the department undertake a wide range of tests including:

  • Blood group and antibody screen (adult and neonates)
  • Antibody identification
  • Direct antiglobulin test
  • Kleihauer test
  • Antibody titration for antenatal patients
  • Cross match
  • Blood products component support


Please see the user handbooks provided for more information on these services or refer to our Test A-Z.
