In the United States, blood transfusions were performed nearly 3 million times during hospitalizations in 2011, making it the most common procedure performed. The rate of hospitalizations with a blood transfusion nearly doubled from 1997, from a rate of 40 stays to 95 stays per 10,000 population.
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.
A patient may be receiving blood due to any number of causes and may have heart or kidney dysfunction which can lead to excess fluid. Upon transfusion of the blood product, the patient is overwhelmed by the excess fluid and develops symptoms related to volume overload. [citation needed]
Cedric Ghevaert, professor in transfusion medicine and consultant haematologist the University of Cambridge and NHS Blood and Transplant, said: “We hope our lab grown red blood cells will last ...
Unlike other blood products demand for platelet transfusions appears to be increasing in several countries around the world. [27] An ageing population, an increase in the number of people with blood cancer, and changes to the management of these cancers are likely the major reasons for the rise in demand for platelets.

A transfusion transmitted infection (TTI) is a virus, parasite, or other potential pathogen that can be transmitted in donated blood through a transfusion to a recipient. The term is usually limited to known pathogens, but also sometimes includes agents such as simian foamy virus which are not known to cause disease.
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.
Platelet transfusion refractoriness is the repeated failure to achieve the desired level of blood platelets in a patient following a platelet transfusion. The cause of refractoriness may be either immune or non-immune. Among immune-related refractoriness, antibodies against HLA antigens are the primary cause.
