The Nine Donors Whose Blood Saves Lives Across Britain

A 26-year-old woman from Bridgwater in Somerset has uncovered 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—without antigens found in nearly 100% of the British population—alongside the uncommon RO blood subtype often seen in people of black African or Caribbean descent. Her donations are so valuable that they are frozen 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 a long-time donor, only recently learned of her VIP status within the NHS, describing the discovery as making her feel very special and honoured.

A Present Above Measure

Stoddart-Stones’s commitment to donating stems from profound personal encounters within her own family. As a baby, she was unwell and needed healthcare support, and her father went on to battle cancer—experiences that fostered within her a strong gratitude for the NHS and its vital services. These pivotal times shaped her determination to support the healthcare system 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 make a tangible difference to individuals nationwide.

“That tiny portion 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 enrolled as a stem cell donor, further extending her potential to help others. Joanne Mathews, head of NHSBT’s National Frozen Blood Bank in Liverpool, spoke of meeting Stoddart-Stones as akin to meeting “royalty,” recognising the extraordinary value of her contributions. Her blood units are distributed solely to patients with matching rare types, ensuring every precious donation reaches those who truly need it.

• Only nine UK donors share Stoddart-Stones’s exact rare blood type combination
• Her blood is frozen for as long as 30 years for use by future patients
• 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

Exploring Rare Blood Classifications

Blood type rarity is determined by the presence or absence of specific antigens—proteins and carbohydrates on the surface of red blood cells that provoke immune reactions. Most people possess widespread antigens such as the U and N antigens present in approximately 99% of the UK population. However, individuals like Stoddart-Stones do not possess these antigens completely, making their blood unsuitable for the vast majority of patients. This genetic variation, whilst uncommon, becomes critically important for those uncommon patients who have the same blood type and require transfusions or surgical procedures.

The National Health Service operates specialised cryopreserved blood facilities to preserve 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 finding compatible blood can prove extraordinarily difficult. Without dedicated rare donor programmes and cryopreserved blood stockpiles, individuals with conditions like sickle cell disease needing frequent blood 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 vulnerable patients.

The Science Behind the Rarity

Stoddart-Stones’s blood group is classified as U negative and N negative, indicating she completely lacks the U and N antigens present in nearly all other people. Additionally, her blood is RO subtype, a rare categorisation more commonly found within communities of black African and Caribbean descent. This combination of missing antigens and uncommon subtype makes her blood extraordinarily valuable for specific patient populations. The genetic basis for these variations remains a subject of continuous medical investigation and research.

When patients receive incompatible blood transfusions, their immune systems attack the foreign red blood cells, potentially triggering severe reactions ranging from fever, jaundice, to organ damage and death. For patients with uncommon blood groups, finding compatible donors before emergency situations arise is essential for survival. NHS Blood and Transplant’s rare blood donor registers locate people with these rare blood groups and keep comprehensive records. This coordinated process ensures that when a patient with an uncommon blood type requires urgent transfusion, compatible units can be located and administered swiftly.

• Antigens are protein structures on red blood cells that define blood transfusion compatibility
• Uncommon blood groups affect less than 0.01% of UK donors in total
• Cryopreserved blood supplies can be preserved for up to 30 years safely

Critical Applications

Mina Stoddart-Stones’s uncommon blood type demonstrates crucial for patients having surgery or demanding emergency medical treatment. Her donations are set aside for patients with matching blood types, ensuring that when a seriously ill person arrives at hospital needing transfusion, matching blood is available. For patients with illnesses including sickle cell disease, which necessitates regular transfusions across their lifetime, access to rare blood donors like Stoddart-Stones constitutes the gap between controlled management and serious medical emergencies. The stored supplies maintained by NHS Blood and Transplant mean that even when emergencies strike unexpectedly, medical teams can act quickly with precisely matched blood.

Without dedicated rare donor programmes, patients with uncommon blood types would face extraordinary delays during health emergencies, potentially resulting in preventable deaths. Stoddart-Stones’s contributions have directly preserved lives across Britain, though she may not discover the identities of those she has assisted. Her choice to give blood consistently, paired with her participation in the stem cell donation scheme, demonstrates strong dedication to helping the health service after her own family benefited from healthcare treatment during childhood illness and her father’s treatment for cancer. This personal motivation encourages numerous rare blood donors to maintain their involvement with national donor schemes
