If a person without a Kidd blood antigen (for example a Jka-Jkb+ patient) receives a Kidd antigen (Jka-antigen for example) in a red blood cell transfusion and forms an alloantibody (anti-Jka); upon subsequent transfusion with Jka-antigen positive red blood cells, the patient may have a delayed hemolytic transfusion reaction as their anti-Jka antibody hemolyzes the transfused Jka-antigen ...
An acute hemolytic transfusion reaction (AHTR), also called immediate hemolytic transfusion reaction, is a life-threatening reaction to receiving a blood transfusion. AHTRs occur within 24 hours of the transfusion and can be triggered by a few milliliters of blood. The reaction is triggered by host antibodies destroying donor red blood cells.
The reaction may occur during, immediately after, or up to 28 days later. An acute reaction is observed within the first 24 hours, whereas a delayed reaction will be observed between 24 hours and 28 days after transfusion. [4]
Kidd antibodies are often capable of binding complement and causing intravascular hemolysis. More often, however, Kidd antibodies cause acute extravascular hemolysis. [7] They are a notorious cause of delayed hemolytic transfusion reactions, and may occur up to a week after transfusion in some instances.

Febrile non-hemolytic transfusion reaction (FNHTR) is the most common type of transfusion reaction. It is a benign occurrence with symptoms that include fever but not directly related with hemolysis. [1] It is caused by cytokine release from leukocytes within the donor product as a consequence of white blood cell breakdown.

Once a woman has antibodies, she is at high risk for a transfusion reaction. [42] For this reason, she must carry a medical alert card at all times and inform all doctors of her antibody status. [citation needed] "Acute hemolytic transfusion reactions may be either immune-mediated or nonimmune-mediated.
