Short Answer
Receiving incompatible blood can cause a severe transfusion reaction that may become life-threatening if not treated immediately.
Detailed Explanation
If incompatible blood is transfused, the recipient's immune system attacks the donated red blood cells.
This may lead to:
- Destruction of red blood cells (haemolysis)
- Fever and chills
- Low blood pressure
- Kidney injury
- Shock
- In severe cases, death
Modern blood banks prevent this by carefully testing blood groups and performing cross-matching before every transfusion.
Key Points
- Incompatible blood transfusions are medical emergencies.
- Hospitals use strict testing procedures to prevent errors.
- ABO and Rh compatibility are always verified.
- Safe blood banking practices greatly reduce this risk.
❤️ Every compatibility test protects a patient's life—and every donor makes safe transfusions possible.
