HYPERSENSITIVITY
Hypersensitivity (also
called hypersensitivity reaction or intolerance) is a set of
undesirable reactions produced by the normal immune system, including allergies and autoimmunity.
These reactions may be damaging, uncomfortable, or occasionally fatal.
Hypersensitivity reactions require a pre-sensitized (immune) state of the host
.
Symptoms
of blood transfusion
Symptoms may include
any of the following:
¨Back pain
¨Bloody urine
¨Chills
¨Fainting or dizziness
¨Fever
¨Flank pain
¨Flushing of the skinHives
¨Shortness of breath.
¨A fast heart rate
¨Low blood pressure.
¨
Symptoms of a
hemolytic transfusion reaction most often appear during or right after the
transfusion. Sometimes, they may develop after several days (delayed reaction).
Treatment
If
symptoms occur during the transfusion, the transfusion must be stopped right
away. Blood samples from the recipient (person getting the transfusion) and
from the donor may be tested to tell whether symptoms are being caused by a
transfusion reaction
