Thirteen-year-old Elliott Wills, a Cornwall resident living with the blood disorder spherocytosis, survived a life-threatening arterial burst after receiving 23 units of blood. According to NHS Blood and Transplant, his recovery highlights an urgent need for donors, as the number of regular O negative and B negative blood donors has fallen by 5% since 2020.
Why Is the Demand for O Negative and B Negative Blood Rising?
The NHS reports that the donor pool for specific blood types is shrinking. There are currently 107,000 regular O negative donors, which is 6,000 fewer than six years ago. This trend is concerning because O negative blood is the universal type that can be administered to any patient in an emergency, as was the case for Elliott Wills when he required seven litres of blood—three times his body’s circulatory volume—after a main artery burst following a spleen and gall bladder removal last October.
You do not need to know your blood type before your first appointment. According to NHS Blood and Transplant, new donors will discover their blood type after their initial donation, potentially identifying them as one of the critical “missing types” currently in high demand.
How Does Spherocytosis Impact Blood Transfusion Needs?
Spherocytosis is an inherited condition that affects red blood cells and frequently leads to severe anaemia. For patients like Elliott, regular transfusions are a medical necessity to maintain health. Gerry Gogarty, director of blood supply for NHS Blood and Transplant, noted that blood donations are essential not only for emergency trauma care but also for the ongoing management of chronic blood disorders. Elliott’s experience demonstrates how a patient can rely on donor blood for both routine maintenance and unexpected, life-saving interventions.

What Are the Risks of Blood Shortages for Patients?
The consequences of a depleted blood supply are direct and severe. During his crisis, Elliott was bleeding faster than medical staff could transfuse blood into his body. His father, Phill Wills, recalled the severity of the situation: “The surgeon said Elliott basically lost all his blood. It was a race against time to get the donated blood into him.” Without the immediate availability of emergency supplies, the outcome for patients facing major haemorrhages or surgical complications becomes significantly more perilous.
Check your eligibility on the official NHS Blood and Transplant website. Whether you have O negative, B negative, or Ro blood types, your contribution can provide a “gift of life” to patients who have exhausted their own circulatory volume during surgery or trauma.
Frequently Asked Questions
Can I donate if I don’t know my blood type?
Yes. You do not need to know your blood type beforehand. The testing process happens after your first donation, and you will be informed of your type shortly thereafter.

Why are O negative and B negative blood types so important?
O negative is the universal donor type, meaning it can be given to anyone in an emergency when there is no time to type-match. B negative is also in high demand due to recent declines in the number of active, regular donors.
How much blood does a person usually need in an emergency?
In extreme cases, such as Elliott Wills’ experience, a patient may require several times their body’s total circulatory volume. Elliott received 23 units of blood, totaling seven litres, to replace what he lost during his emergency surgery.
How can I support the blood supply?
You can register to give blood through the NHS Blood and Transplant service. They are currently seeking more donors with O negative, B negative, and Ro blood types to stabilize supply levels.
