The Nine Donors Whose Blood Saves Lives Across Britain

March 15, 2026 · admin

A 26-year-old woman from Bridgwater in Somerset has discovered she carries one of the rarest blood types in Britain, with only nine other donors across the whole of the UK sharing her exact combination. Mina Stoddart-Stones carries blood that is U negative and N negative—without antigens present in nearly 100% of the British population—alongside the uncommon RO blood subtype often seen in people of African or Caribbean descent. Her donations are so precious that they are stored at low temperature for up to 30 years by NHS Blood and Transplant, kept solely for patients with compatible rare blood groups requiring surgery or regular transfusions. Stoddart-Stones, who has been donating for years, only recently learned of her VIP status within the health service, describing the discovery as making her feel very special and honoured.

A Gift Beyond Measure

Stoddart-Stones’s drive to contribute stems from deeply personal experiences within her own family. As a baby, she was poorly and required medical care, and her father subsequently fought cancer—experiences that fostered within her a deep respect for the NHS and its critical care. These pivotal times strengthened her commitment to support the medical service that had been there for those close to her during their darkest hours. Now, with her unique blood classification, she has discovered a particularly effective way to create real change to individuals nationwide.

“That tiny amount that I can do assisting them as much as they’ve helped my family,” she reflected on her motivation. Beyond blood donation alone, Stoddart-Stones has also registered as a stem cell donor, additionally broadening her potential to help others. Joanne Mathews, director of NHSBT’s National Frozen Blood Bank in Liverpool, talked about meeting Stoddart-Stones as akin to meeting “royalty,” acknowledging the extraordinary value of her contributions. Her blood units are allocated exclusively to patients with corresponding rare types, ensuring every precious donation reaches those who truly need it.

  • Only nine UK donors share Stoddart-Stones’s rare exact blood type combination
  • Her blood is preserved for up to 30 years for future patient use
  • Rare blood donors comprise only 0.01% of the UK’s blood donor population of 800,000
  • She is also listed with the stem cell donor panel

Exploring Uncommon Blood Groups

Blood type rarity is determined by the presence or absence of specific antigens—proteins and sugars on the surface of red blood cells that trigger immune responses. Most individuals have common antigens such as the U and N antigens found in approximately 99% of the UK population. However, people such as Stoddart-Stones do not possess these antigens entirely, making their blood unsuitable for the overwhelming majority of patients. This genetic variation, whilst uncommon, becomes critically important for those uncommon patients who share the same blood type and need blood transfusions or surgical intervention.

The National Health Service maintains specialised cryopreserved blood facilities to store these highly uncommon donations for extended periods, guaranteeing availability when required. Patients with rare blood types face significant challenges during medical emergencies or when undergoing planned operations, as locating suitable blood can become exceptionally challenging. Without dedicated rare donor programmes and frozen blood reserves, individuals with conditions like sickle cell disease requiring regular transfusions would have markedly restricted therapeutic choices. The NHS’s forward-thinking strategy to identifying and supporting rare blood donors has revolutionised care for these at-risk individuals.

The Research Behind the Scarcity

Stoddart-Stones’s blood type is classified as U negative and N negative, meaning she completely lacks the U and N antigens found in nearly all other people. Additionally, her blood is RO sub-type, a rare classification more commonly found within populations of black African and Caribbean descent. This combination of missing antigens and uncommon subtype makes her blood exceptionally valuable for particular patient groups. The genetic foundation for these variations remains a matter of ongoing medical research and study.

When patients undergo incompatible blood transfusions, their body’s defences attack the incompatible blood cells, potentially triggering serious complications ranging from fever and jaundice to organ failure and death. For patients with rare blood types, locating suitable donors before emergency situations arise is essential for survival. NHS Blood and Transplant’s rare blood donor registers identify individuals with these rare blood groups and keep comprehensive records. This systematic approach ensures that when a patient with rare blood requires emergency blood transfusion, compatible units can be found and given swiftly.

  • Antigens are protein structures on erythrocytes that establish blood type matching
  • Uncommon blood groups affect less than 0.01% of British blood donors in total
  • Cryopreserved blood supplies can be maintained for up to 30 years in a secure manner

Critical Applications

Mina Stoddart-Stones’s unusual blood type shows essential for patients undergoing surgery or demanding urgent treatment. Her donations are kept solely for individuals with matching blood types, guaranteeing when a critical patient arrives at hospital needing transfusion, matching blood is on hand. For patients with illnesses including sickle cell disease, which requires frequent blood transfusions for life, access to rare blood donors like Stoddart-Stones represents the difference between manageable treatment and serious medical emergencies. The stored supplies maintained by NHS Blood and Transplant ensure that even when emergencies happen suddenly, medical teams can act quickly with carefully matched blood.

Without established rare donor schemes, patients with uncommon blood types would encounter substantial waiting times during medical crises, possibly causing avoidable fatalities. Stoddart-Stones’s contributions have directly rescued individuals across Britain, though she may remain unaware of the individuals whom she has helped. Her commitment to regular donation, combined with her involvement with the stem cell register, shows genuine commitment to supporting the NHS after her family received medical care during early health problems and her father’s treatment for cancer. This personal motivation drives many uncommon blood group donors to sustain their participation with national donation initiatives

Condition Treatment Requirement
Sickle Cell Disease Regular transfusions to manage chronic anaemia and prevent complications
Thalassaemia Major Frequent blood transfusions to replace defective red blood cells
Surgical Operations Compatible blood available for transfusion during planned procedures
Haemolytic Transfusion Reactions Specially matched rare blood to prevent immune system complications

The Cryopreserved Blood Bank Network

NHS Blood and Transplant manages the National Frozen Blood Bank in Liverpool, where Joanne Mathews and her team maintain meticulous records of donors with rare blood types and their valuable donations. Blood units from rare donors like Stoddart-Stones are preserved and kept for as long as 30 years, establishing a national supply that can be activated within hours when needed. This freezing capacity reshapes the approach of rare blood services, allowing the NHS to preserve supplies that would otherwise break down within weeks. The Liverpool facility serves as the cornerstone of Britain’s rare blood security systems.

Stoddart-Stones plays a significant role in the National Frozen Blood Bank’s records, with her name and blood type information carefully catalogued to ensure her donations reach only patients with corresponding rare blood types. Mathews described meeting Stoddart-Stones as encountering “nobility,” highlighting the remarkable standing these donors hold within the health service. The frozen blood network spans the entire country, linking exceptional donors with patients across Britain who urgently require their vital donations. This sophisticated system illustrates how modern medical science can preserve precious biological resources for emergencies ahead.

Personal Motivation and Community Impact

For Mina Stoddart-Stones, the choice to give blood extends far beyond a simple health service contribution. Her motivation is deeply rooted in lived experience, influenced by her childhood health struggles and her father’s struggle with cancer. After seeing firsthand the profound effect of healthcare, she feels a profound sense of obligation to return support to the health service that helped her loved ones through their darkest times. This emotional connection converts her rare donations from a healthcare exchange into a heartfelt contribution of appreciation and compassion with others facing serious health challenges.
