The science of blood transfusion dates to the first decade of the 20th century, with the discovery of distinct blood types leading to the practice of mixing some blood from the donor and the receiver before the transfusion (an early form of cross-matching).
In transfusion medicine, transfusion-associated circulatory overload (aka TACO) is a transfusion reaction (an adverse effect of blood transfusion) resulting in signs or symptoms of excess fluid in the circulatory system (hypervolemia) within 12 hours after transfusion. [2]

Transfusion-dependent anemia is a form of anemia characterized by the need for continuous blood transfusion. It is a condition that results from various diseases, and is associated with decreased survival rates. [1] [2] Regular transfusion is required to reduce the symptoms of anemia by increasing functional red blood cells and hemoglobin count.
Blood compatibility testing is routinely performed before a blood transfusion.The full compatibility testing process involves ABO and RhD (Rh factor) typing; screening for antibodies against other blood group systems; and crossmatching, which involves testing the recipient's blood plasma against the donor's red blood cells as a final check for incompatibility.
The incidence of TA-GvHD in immunocompromised patients receiving blood transfusions is estimated to be 0.1–1.0%, and mortality around 80–90%. Mortality is higher in TA-GvHD than in GvHD associated with bone marrow transplantation , where the engrafted lymphoid cells in the bone marrow are of donor origin (in autotransplant) and therefore ...
