Rotation thrombelastogram (ROTEM®/TEG®) assays allow rapid global assessment of hemostatic function using whole blood. Since published data about the effects of automated red cell collection on coagulation system are scarce, we aimed to investigate the effects of 2-RBC apheresis on donor's coagulation system using ROTEM® assays. In INTEM assay, CFT was significantly shortened 24h after apheresis compared with baseline value (p<0.05) and MCF was significantly prolonged immediately after apheresis and 24h after apheresis compared with baseline value (p<0.05 and p<0.01, respectively). In EXTEM assay, CFT was significantly prolonged immediately after apheresis and 24h after apheresis compared with baseline value (p=0.001 and p<0.001, respectively) and MCF was significantly prolonged 24h after apheresis compared with baseline value (p<0,001). Our results demonstrate thromboelastographic signs of hypercoagulability in donors undergoing 2-RBC apheresis.

Blood Transfusion

Blood transfusion is a critical medical procedure that saves lives and treats various medical conditions. It involves transferring blood from a donor to a recipient. This process requires a thorough understanding of the ABO blood group system and its associated antigens and antibodies.
Blood Transfusion Overview
A blood transfusion is a medical procedure used to replace blood lost due to injury, surgery, or to treat conditions such as anemia or cancer. During a transfusion, donor blood is...

Blood Transfusion and Agglutination

Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
