Two reviews in people with blood cancers receiving intensive chemotherapy or a stem cell transplant found that overall giving platelet transfusions when the platelet count is less than 10 x 10 9 /L compared to giving platelet transfusions when the platelet count is less than 20 or 30 x 10 9 /L had no effect on the risk of bleeding.

Transfusion of a single unit also encourages less wastage of blood products [5] and can be cost-effective. Single unit transfusion can be as part of an institutional or national guidelines [3] and instituted with the help of a transfusion committee or transfusion practitioner. Education of medical staff is important and catch phrases such as ...
In a typical set of rules, a platelet donor must weigh at least 50 kg (110 lb) and have a platelet count of at least 150 x 10 9 /L (150,000 platelets per mm³). [2] One unit has greater than 3×10 11 platelets. Therefore, it takes 2 liters of blood having a platelet count of 150,000/mm³ to produce one unit of platelets.
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.
On rare occasions, blood products are contaminated with bacteria. This can result in a life-threatening infection known as transfusion-transmitted bacterial infection. The risk of severe bacterial infection is estimated, as of 2020, at about 1 in 2,500 platelet transfusions, and 1 in 2,000,000 red blood cell transfusions. [44]
It also helps to improve the oxygen saturation in blood. It can be stored at 2.0 °C-6.0 °C for 35–45 days. Platelet transfusion is transfused to those with low platelet count. Platelets can be stored at room temperature for up to 5–7 days. Single donor platelets, which have a more platelet count but it is bit expensive than regular.
Autotransfusion is a process wherein a person receives their own blood for a transfusion, instead of banked allogenic (separate-donor) blood.There are two main kinds of autotransfusion: Blood can be autologously "pre-donated" (termed so despite "donation" not typically referring to giving to one's self) before a surgery, or alternatively, it can be collected during and after the surgery using ...
In 1665 another English doctor Richard Lower successfully used blood transfusion between dogs to keep them alive. [1] Karl Landsteiner is recognized as the father of transfusion medicine. Landsteiner is credited with the first classification of human blood into the four types (A, B, AB, O) of the ABO blood group system.
