The universal donor blood group is O.
- Blood groups are classified based on the presence or absence of certain antigens on the surface of red blood cells.
- The ABO blood group system categorizes blood into four main groups: A, B, AB, and O.
- When it comes to blood transfusions, compatibility between the donor and recipient blood types is essential to avoid adverse reactions.
- The universal donor is the blood type that can be safely transfused to individuals with any other blood type.
- The universal donor blood group is O because it lacks both A and B antigens on the surface of red blood cells.
- Since there are no A or B antigens, the O blood type does not trigger an immune response in recipients with any other blood type.
- In addition to being the universal donor, the O blood type can only receive blood from other O blood types.
- It is important to note that while O- (O negative) is considered the true universal donor because it can be transfused to any blood type, O+ (O positive) is also commonly used as a universal donor in situations where O- blood is not available.
- Individuals with the O blood type are encouraged to consider donating blood as their blood can potentially be used to save lives in emergencies and surgeries.
