Hematology and Blood Disorders

Blood transfusion

Blood transfusion is the process of receiving whole blood or blood products into one’s systemic circulation intravenously. Blood transfusion is usually done in cases of deficiencies, to increase the oxygen saturation, during accidents or during surgery, to treat hematologic conditions such as severe anemia, leukemia, and sickle cell disease. Transfusion may include injection of whole blood or components such as red blood cells, white blood cells, plasma, platelets or clotting factors. Hence a very systematic protocol is followed for blood transfusion which includes processing and testing the donor’s blood for possible infectious disorders, particularly for viruses such as Hepatitis B and C, HIV, and West Nile Virus. The system should include monitoring, identification, reporting, investigation and analysis of adverse events near-misses and reactions related to transfusion and manufacturing. Research and Development in this area of Hematology is hence considered a very important aspect.
