Which blood group is universal donor?
The blood group that is considered a universal donor is blood group O-negative (O-). This means that people with this blood group can donate blood to all other blood groups without an immune response. This makes O-negative blood essential in emergencies and in blood transfusions where the recipient’s blood type is not directly known.
Why is blood type O-negative the universal donor?
Blood group O-negative contains no A or B antigens on the red blood cells and no rhesus factor (Rh-). As a result, it is not recognised as foreign by the immune systems of other blood groups, allowing it to be safely administered to anyone regardless of blood type. This prevents rejection reactions and makes it a crucial blood group in medical emergencies.

Why is O-negative blood so important?
Blood group O-negative is often used in:
- Emergency care and trauma: In acute situations, such as serious accidents or operations, there is often no time to determine the patient’s blood type. O-negative blood can be administered immediately.
- Blood banks and hospitals: As this blood group is scarce, donation of O-negative blood is strongly encouraged to have a constant supply available.
- Newborns: Premature babies and newborns with blood problems can sometimes only safely receive O-negative blood.
How many people have blood type O-negative?
Only 6-7% of the world’s population has blood group O-negative, making it a relatively rare blood group. This makes it all the more important that people with this blood group donate regularly to ensure sufficient supplies for emergencies.
Can people with O-negative blood receive blood from anyone?
No, people with blood type O-negative can only receive blood from other O-negative donors. Because their blood contains no antigens, their immune system will reject blood with A, B or Rh antigens. This makes it extra important for O-negative patients to know where to go for a blood transfusion.
Conclusion
Blood type O-negative is the universal donor because it can be given to anyone without immune reactions. This makes it indispensable in emergency situations and medical treatments. Because of the relative rarity of O-negative blood, it is crucial that people with this blood group register as blood donors to save lives. Take a blood group test to find out your blood group.
