A 26-year-old woman from Bridgwater in Somerset has found out she possesses one of the most uncommon blood groups in Britain, with only nine other blood donors across the whole of the UK sharing her exact blood type composition. 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 black African or Caribbean descent. Her donations are so valuable 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 just discovered of her VIP status within the health service, describing the discovery as making her feel particularly valued and privileged.
A Token Above Measure
Stoddart-Stones’s drive to contribute originates in profound personal encounters within her own family. As a baby, she was unwell and required medical care, and her father subsequently fought cancer—experiences that created in her a profound appreciation for the NHS and its life-saving work. These pivotal times strengthened her commitment to support the medical service that had helped her family members during their darkest hours. Now, with her uncommon blood group, she has identified a distinctly impactful way to create real change to people throughout the UK.
“The small amount that I can do helping 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 expanding her potential to help others. Joanne Mathews, head of NHSBT’s National Frozen Blood Bank in Liverpool, talked about 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 possess Stoddart-Stones’s rare exact blood type combination
- Her blood is frozen for up to 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 listed with the stem cell donor panel
Understanding Rare Blood Types
Blood type rarity is established through the presence or absence of particular antigens—proteins and carbohydrates on the surface of red blood cells that provoke immune reactions. Most people possess common antigens such as the U and N antigens found in approximately 99% of the UK population. However, people such as Stoddart-Stones lack these antigens entirely, making their blood incompatible with the overwhelming majority of patients. This genetic variation, whilst uncommon, proves essential for those rare patients who have the same blood type and require transfusions or surgical procedures.
The National Health Service operates specialised cryopreserved blood facilities to safeguard these highly uncommon donations for extended periods, ensuring they remain available when needed. Patients with rare blood types encounter considerable difficulties in emergency situations or when undergoing planned operations, as finding compatible blood can become exceptionally challenging. In the absence of specialist rare donor initiatives and frozen blood reserves, patients suffering from conditions such as sickle cell disease requiring regular transfusions would face severely limited treatment options. The NHS’s proactive approach to identifying and supporting uncommon blood donor populations has revolutionised care for these vulnerable patients.
The Science Underlying the Rarity
Stoddart-Stones’s blood group is classified as U negative and N negative, meaning she entirely lacks the U and N antigens present in nearly all other people. Additionally, her blood is RO sub-type, a rare classification more frequently observed in 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 foundation for these variations continues to be a subject of ongoing medical research and study.
When patients receive incompatible blood transfusions, their immune systems attack the foreign red blood cells, which can cause serious complications ranging from fever, jaundice, to organ damage and death. For patients with uncommon blood groups, locating suitable donors before emergencies occur is vital for their survival. NHS Blood and Transplant’s rare donor panels locate people with these rare blood groups and maintain detailed registries. This coordinated process ensures that when a patient with an uncommon blood type requires emergency blood transfusion, suitable blood units can be located and administered swiftly.
- Antigens are proteins on erythrocytes that establish blood transfusion compatibility
- Uncommon blood groups occur in fewer than 0.01% of UK donors in total
- Frozen blood reserves can be maintained for as long as 30 years without degradation
Critical Applications
Mina Stoddart-Stones’s unusual blood type proves crucial for patients facing surgery or demanding emergency treatment. Her donations are kept solely for individuals with compatible blood types, making certain when a critical patient arrives at the hospital needing a blood transfusion, compatible blood is on hand. For patients with disorders like sickle cell disease, which demands ongoing transfusions throughout their lives, access to rare blood donors like Stoddart-Stones means the gap between controlled management and critical health risks. The preserved blood stocks held by NHS Blood and Transplant ensure that even when emergencies strike unexpectedly, medical teams can respond promptly with precisely matched blood.
Without specialist rare blood programmes, people requiring uncommon blood types would face extraordinary delays during medical crises, which could lead to deaths that could be prevented. Stoddart-Stones’s contributions have directly saved lives across Britain, though she may never know the individuals whom she has helped. Her decision to donate regularly, paired with her engagement in the stem cell register, demonstrates strong dedication to supporting the NHS after her family received healthcare treatment during early health problems and her father’s cancer treatment. This personal impetus drives many uncommon blood group donors to continue their engagement with national donor schemes
| 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 System
NHS Blood and Transplant manages the National Frozen Blood Bank in Liverpool, where Joanne Mathews and her team maintain meticulous records of rare blood donors and their precious donations. Blood units from rare donors like Stoddart-Stones are stored frozen for approximately 30 years, creating a national stockpile that can be deployed within hours when needed. This frozen storage capability revolutionises the provision of rare blood supply, allowing the NHS to preserve supplies that would otherwise break down within weeks. The Liverpool facility forms the foundation of the UK’s rare blood security framework.
Stoddart-Stones plays a significant role in the National Frozen Blood Bank’s records, with her name and blood type information meticulously recorded to ensure her donations go exclusively to patients with matching rare types.
