The Nine Donors Whose Blood Saves Lives Across Britain

A 26-year-old woman from Bridgwater in Somerset has discovered she carries one of the most uncommon blood groups in Britain, with only nine other blood donors across the entire UK who share her exact combination. Mina Stoddart-Stones carries blood that is U negative and N negative—lacking antigens found in nearly 100% of the British population—alongside the uncommon RO blood subtype often found in people of African or Caribbean descent. Her donations are so precious that they are frozen for up to 30 years by NHS Blood and Transplant, kept solely for patients with matching rare blood types requiring surgery or regular transfusions. Stoddart-Stones, who has been donating for years, only recently learned of her VIP status within the NHS, describing the realisation as making her feel very special and honoured.

A Present Beyond Measure

Stoddart-Stones’s drive to contribute originates in profound personal encounters within her own family. As a baby, she was poorly and underwent medical treatment, and her father later battled cancer—experiences that instilled in her a deep respect for the NHS and its vital services. These pivotal times strengthened her commitment to contribute to the medical service that had supported her loved ones during their most difficult times. Now, with her unique blood classification, she has discovered a particularly effective way to deliver meaningful impact to people throughout the UK.

“That small amount that I can do helping them as much as they’ve helped my family,” she discussed her motivation. Beyond blood donation alone, Stoddart-Stones has also signed up as a stem cell donor, additionally broadening her potential to help others. Joanne Mathews, manager of NHSBT’s National Frozen Blood Bank in Liverpool, talked about meeting Stoddart-Stones as akin to meeting “royalty,” noting the extraordinary value of her contributions. Her blood units are assigned exclusively to patients with rare matching types, making certain 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 frozen for as long as 30 years for future patient use
• Rare blood donors make up only 0.01% of the UK’s blood donor population of 800,000
• She is also registered on the stem cell donor panel

Learning about Uncommon Blood Groups

Blood type rarity is determined by the presence or lack of particular antigens—proteins and sugars on the surface of red blood cells that trigger immune responses. Most individuals have widespread antigens such as the U and N antigens found in approximately 99% of the UK population. However, individuals like Stoddart-Stones lack these antigens completely, making their blood unsuitable for the vast majority of patients. This genetic variation, whilst rare, proves essential for those rare patients who have the same blood type and require transfusions or surgical procedures.

The National Health Service manages specialised cryopreserved blood facilities to preserve these highly uncommon donations for extended periods, guaranteeing availability when needed. Patients with uncommon blood groups encounter considerable difficulties in emergency situations or when having scheduled procedures, as locating suitable blood can become exceptionally challenging. In the absence of specialist rare donor initiatives and frozen blood reserves, individuals with conditions like sickle cell disease requiring regular transfusions would have markedly restricted therapeutic choices. The NHS’s proactive approach to identifying and supporting rare blood donors has transformed treatment for these at-risk individuals.

The Research Behind the Uncommon Nature

Stoddart-Stones’s blood type is classified as U negative and N negative, meaning she entirely lacks the U and N antigens found in nearly all other people. Additionally, her blood is RO subtype, a rare categorisation more frequently observed in populations of black African and Caribbean descent. This combination of missing antigens and uncommon subtype makes her blood exceptionally valuable for specific patient populations. The genetic foundation for these variations remains a matter of continuous medical investigation and research.

When patients receive incompatible blood transfusions, their immune systems attack the incompatible blood cells, which can cause severe reactions ranging from fever, jaundice, to organ failure and death. For patients with rare blood types, finding compatible donors before emergencies occur is essential for survival. NHS Blood and Transplant’s rare donor panels locate people with these rare blood groups and keep comprehensive records. This systematic approach ensures that when a patient with an uncommon blood type requires urgent transfusion, suitable blood units can be found and given swiftly.

• Antigens are proteins on red blood cells that define blood type matching
• Uncommon blood groups affect fewer than 0.01% of British blood donors in total
• Stored frozen blood can be preserved for as long as 30 years without degradation

Critical Applications

Mina Stoddart-Stones’s uncommon blood type proves essential for patients having surgery or demanding urgent treatment. Her donations are reserved exclusively for patients with compatible blood types, guaranteeing when a patient in crisis arrives at the hospital needing transfusion, compatible blood is available. For patients with illnesses including sickle cell disease, which necessitates frequent blood transfusions across their lifetime, availability of rare blood donors like Stoddart-Stones represents the difference between controlled management and life-threatening complications. The frozen reserves kept by NHS Blood and Transplant mean that even when crises occur without warning, medical teams can act quickly with carefully matched blood.

Without established rare donor schemes, patients with uncommon blood types would experience significant delays during health emergencies, possibly causing deaths that could be prevented. Stoddart-Stones’s work has substantially rescued individuals across Britain, though she may not discover the identities of those she has helped. Her commitment to regular donation, alongside her involvement with the stem cell register, reflects a deep commitment to supporting the NHS after her relatives gained healthcare treatment during childhood illness and her father’s treatment for cancer. This individual drive prompts many rare blood donors to continue their engagement with national donor schemes

The Cryopreserved Blood Bank System

NHS Blood and Transplant operates the National Frozen Blood Bank in Liverpool, where Joanne Mathews and her team keep detailed records of rare blood donors and their precious donations. Blood units from rare donors like Stoddart-Stones are preserved and kept for up to 30 years, forming a national supply that can be mobilised within hours when needed. This frozen storage capability transforms the landscape of rare blood provision, allowing the NHS to maintain supplies that would otherwise break down within weeks. The Liverpool facility forms the foundation of Britain’s rare blood security systems.

Stoddart-Stones features prominently 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 spoke of encountering Stoddart-Stones as encountering “nobility,” reflecting the exceptional status these donors hold within the health service. The frozen blood network extends across the nation, connecting rare donors with patients throughout the UK who urgently require their life-saving contributions. This sophisticated system demonstrates how modern medical science can preserve valuable blood supplies for future emergencies.

Individual Drive and Community Impact

For Mina Stoddart-Stones, the decision to donate blood extends far beyond a simple health service contribution.
