Transfusion Reaction

A transfusion reaction is the body's unwanted response when it receives blood or blood components from another person, and it can range from mild symptoms to conditions that require immediate attention.

Why does it happen? It is usually related to differences between the donated blood and that of the recipient, or to the immune system's response to foreign components.

Possible manifestations:

• Chills, fever, or a feeling of general malaise.
• Itching, hives, or redness of the skin.
• Difficulty breathing or pressure in the chest.

Who evaluates it? The hematologist, a specialist in blood and its disorders, is the one who studies this type of reaction; when there is skin involvement the dermatologist may also take part. If you had symptoms during or after a transfusion, the most sensible thing is to discuss it with a professional to review your case calmly.
