Blood Transfusion: Ensuring Donor-Recipient Blood Compatibility

Why is it important to ensure blood compatibility before a transfusion takes place?

A. To prevent allergic reactions

B. To avoid harmful blood transfusion reactions

C. To save time and resources

D. To improve the patient's overall health

Answer:

B. To avoid harmful blood transfusion reactions

Before a blood transfusion can occur, it is crucial to ensure compatibility between the donor's and recipient's blood to avoid harmful reactions. This process involves determining the blood types, cross-matching cells and serums, and occasionally performing a minor cross-match.

The discovery of major human blood groups by Karl Landsteiner in 1900 led to the recognition of the importance of blood compatibility. Prior to this discovery, blood transfusions often resulted in severe reactions and even death due to mismatched blood types.

By conducting tests to determine blood compatibility, healthcare providers can significantly reduce the risks associated with blood transfusions and ensure the safety and well-being of the patients.
