Short Answer
Rare blood groups are blood types that occur in only a very small percentage of the population, making compatible blood difficult to find.
Detailed Explanation
A blood group is considered rare when very few people possess it or when compatible donors are extremely limited.
Examples include:
- Bombay Blood Group (hh)
- Certain rare Rh variants
- Other uncommon antigen combinations
People with rare blood groups may require specially matched donors during transfusions. This is why rare donor registries are maintained by many blood services.
Key Points
- Rare blood groups occur in very few people.
- Finding compatible donors may be challenging.
- Special donor registries help locate suitable donors.
- Early identification can save valuable time during emergencies.
❤️ Your rare blood group could make you one of the few people capable of saving another rare patient's life.
