NHS Blood and Transplant

NHS Blood and Transplant (NHSBT) collects blood from volunteer donors across England and North Wales. Donors undergo a health questionnaire and a finger‑prick test to check haemoglobin levels before donation. Whole blood is collected into sterile bags and transported to processing centres under temperature‑controlled conditions. At the centres, blood is tested for a range of infectious agents, including hepatitis B and C, HIV and syphilis, to ensure safety. After testing, the blood is separated into its components: red blood cells, platelets, plasma and cryoprecipitate. Each component is stored under specific conditions to maintain viability for clinical use. NHSBT also collects plasma for fractionation into medicinal products such as immunoglobulins and albumin. The supplied components are issued to hospitals for use in surgery, obstetrics, oncology and emergency care.

The organisation runs a network of fixed donor centres located in cities and towns, supplemented by mobile units that visit workplaces, schools and community events. Donation sessions are scheduled throughout the year to maintain a steady supply of blood products. NHSBT operates specialised laboratories that perform blood group genotyping, antibody identification and compatibility testing for patients requiring transfusions. In addition to routine blood supply, NHSBT provides therapeutic apheresis services that remove or collect specific blood components for patients with autoimmune or neurological disorders. The organisation manages the NHS Organ Donor Register, which records the donation wishes of millions of members of the public. When a potential donor is identified, NHSBT coordinates with transplant centres to organise organ retrieval, preservation and transport. NHSBT also oversees the UK Stem Cell Register, which links volunteer donors with patients needing hematopoietic stem cell transplantation. Through these activities the organisation supports a wide range of clinical pathways, from elective surgery to life‑saving emergency interventions.

As a special health authority, NHSBT is directly accountable to the Secretary of State for Health and Social Care and operates under the governance framework of the Department of Health and Social Care. It is not a subsidiary of any commercial parent organisation; instead it provides oversight and operational delivery for the blood and transplant sectors. NHSBT sets and enforces quality and safety standards for blood collection, testing, processing and distribution, acting as the de facto regulator for these services in England and North Wales. The organisation houses the UK Stem Cell Registry and the British Bone Marrow Registry, giving it specialist expertise in immunogenetics and donor‑patient matching. NHSBT runs research and development programmes that investigate new methods of blood preservation, pathogen reduction and organ perfusion technologies. During public health emergencies, such as the COVID‑19 pandemic, NHSBT mobilised rapidly to collect convalescent plasma and support clinical trials of potential therapies. It also provides training and education for healthcare professionals involved in transfusion medicine and transplantation. By combining service delivery, standard‑setting and scientific innovation, NHSBT plays a central role in maintaining the safety and effectiveness of the NHS blood and transplant supply chain.
