A blood type is a classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells (RBCs). These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system. Some of these antigens are also present on the surface of other types of cells of various tissues. Several of these red blood cell surface antigens can stem from one allele and collectively form a blood group system.
Blood transfusion is the process of transferring blood products into a person's circulation intravenously. Transfusions are used for various medical conditions to replace lost components of the blood. Early transfusions used whole blood, but modern medical practice commonly uses only components of the blood, such as red blood cells, plasma, platelets, and other clotting factors. White blood cells are transfused only in very rare circumstances, since granulocyte transfusion has limited applications. Whole blood has come back into use in the setting of trauma.
Transfusion medicine is the branch of medicine that encompasses all aspects of the transfusion of blood and blood components including aspects related to hemovigilance. It includes issues of blood donation, immunohematology and other laboratory testing for transfusion-transmitted diseases, management and monitoring of clinical transfusion practices, patient blood management, therapeutic apheresis, stem cell collections, cellular therapy, and coagulation. Laboratory management and understanding of state and federal regulations related to blood products are also a large part of the field.
Charles Richard Drew was an American surgeon and medical researcher. He researched in the field of blood transfusions, developing improved techniques for blood storage, and applied his expert knowledge to developing large-scale blood banks early in World War II. This allowed medics to save thousands of Allied forces' lives during the war. As the most prominent African American in the field, Drew protested against the practice of racial segregation in the donation of blood, as it lacked scientific foundation, and resigned his position with the American Red Cross, which maintained the policy until 1950.
Whole blood (WB) is human blood from a standard blood donation. It is used in the treatment of massive bleeding, in exchange transfusion, and when people donate blood to themselves. One unit of whole blood brings up hemoglobin levels by about 10 g/L. Cross matching is typically done before the blood is given. It is given by injection into a vein.
A blood bank is a center where blood gathered as a result of blood donation is stored and preserved for later use in blood transfusion. The term "blood bank" typically refers to a department of a hospital usually within a clinical pathology laboratory where the storage of blood product occurs and where pre-transfusion and blood compatibility testing is performed. However, it sometimes refers to a collection center, and some hospitals also perform collection. Blood banking includes tasks related to blood collection, processing, testing, separation, and storage.
A blood donation occurs when a person voluntarily has blood drawn and used for transfusions and/or made into biopharmaceutical medications by a process called fractionation. A donation may be of whole blood, or of specific components directly (apheresis). Blood banks often participate in the collection process as well as the procedures that follow it.
The Canadian Red Cross Society is a Canadian humanitarian charitable organization, and one of 192 national Red Cross and Red Crescent societies. The organization receives funding from both private donations and from Canadian government departments.
Canadian Blood Services is a non-profit charitable organization that is independent from the Canadian government. The Canadian Blood Services was established as Canada's blood authority in all provinces and territories except for Quebec in 1998. The federal, provincial and territorial governments created the Canadian Blood Services through a memorandum of understanding. Canadian Blood Services is funded mainly through the provincial and territorial governments.
Héma-Québec is a non-profit organization that supplies blood and other biological products of human origin to hospitals for the Canadian province of Quebec. The organization's headquarters is located in the Montreal borough of Saint-Laurent, Quebec, and it was created on March 26, 1998, as a successor to the Canadian Red Cross Blood Program and the Canadian Blood Agency on recommendation of the Krever Commission.
NHS Blood and Transplant is an executive special health authority of the United Kingdom's Department of Health and Social Care. It was established on 1 October 2005 to take over the responsibilities of two separate NHS agencies: UK Transplant, founded by Dr. Geoffrey Tovey in 1972, and the National Blood Service. Its remit is to provide a reliable, efficient supply of blood, organs and associated services to the NHS. Since NHSBT was established, the organisation has maintained or improved the quality of the services delivered to patients, stabilised the rising cost of blood, and centralised a number of corporate services.
The International Society of Blood Transfusion (ISBT) is a scientific society founded in 1935 which promotes the study of blood transfusion and provides information about the ways in which blood transfusion medicine and science can best serve patients' interests. The society's central office is in Amsterdam, and there are around 1900 members in 103 countries. As of June 2024, the president of the ISBT is Pierre Tiberghien.
The Health Sciences Authority (HSA) is a statutory board under the Ministry of Health of the Government of Singapore. It is a multi-disciplinary agency responsible for applying medical, pharmaceutical, and scientific expertise to protect and advance public health and safety.
Packed red blood cells, also known as packed cells, are red blood cells that have been separated for blood transfusion. The packed cells are typically used in anemia that is either causing symptoms or when the hemoglobin is less than usually 70–80 g/L. In adults, one unit brings up hemoglobin levels by about 10 g/L. Repeated transfusions may be required in people receiving cancer chemotherapy or who have hemoglobin disorders. Cross-matching is typically required before the blood is given. It is given by injection into a vein.
Nepal Red Cross Society is an independent, volunteer-based and humanitarian organization that delivers humanitarian service and support to the vulnerable people in an impartial and neutral manner. It came into being on 4 September 1963. Nepal Red Cross Society was officially registered in Nepal after Nepal Government acceded to the Geneva Conventions. Having been recognized by the International Committee of the Red Cross (ICRC) and affiliated to International Federation of Red Cross and Red Crescent Societies (IFRC) on 1 October 1964.
World Blood Donor Day (WBDD) is held on June 14 each year. The event was organised for the first time in 2004, by four core international organizations: the World Health Organization, the International Federation of Red Cross and Red Crescent Societies; the International Federation of Blood Donor Organizations (IFBDO) and the International Society of Blood Transfusion (ISBT) to raise awareness of the need for safe blood and blood products, and to thank blood donors for their voluntary, life-saving gifts of blood. World Blood Donor Day is one of 11 official global public health campaigns marked by the World Health Organization (WHO), along with World Health Day, World Chagas Disease Day, World Tuberculosis Day, World Immunization Week, World Patient Safety Day, World Malaria Day, World No Tobacco Day, World Hepatitis Day, World Antimicrobial Awareness Week and World AIDS Day.
Blood transfusion was first performed in Sri Lanka in late 1950. It became more widely known to the public in 1959 after the assassination of Prime Minister S.W.R.D. Bandaranaike, when an appeal was made to the public to donate blood. The country's blood bank system has since expanded from a single initial site to multiple blood donation centres and laboratories nationwide, operating under the auspices of the National Blood Transfusion Service (NBTS). As of 2014, the NBTS collects over 350,000 voluntary blood donations every year.
Frederic Duran i Jordà was a Spanish medical doctor, pioneer hematology and hemotherapy. He created the first transfusion service in the world in Barcelona in 1936 at the beginning of the Spanish Civil War. Previously there were blood banks, where donated blood to be transfused was stored. Dr. Duran i Jordà created a methodology that would serve to collect massive blood donations and be transfused distance, in this case the front lines of the Spanish Civil War. This method was subsequently applied in World War II.
Blood donations in India are conducted by organisations and hospitals through blood donation camps. Donors can also visit blood banks in hospitals to donate blood. Efforts by the government and advocacy groups over the years have helped bridge the gap between demand and supply. The regulatory framework for blood donation and blood bank management rests with the Central Drugs Standard Control Organisation, while technical bodies like the National Blood Transfusion Council and National AIDS Control Organisation formulate guidelines and recommendations for transfusion medicine and blood bank management. Challenges persist with regards to regulation of blood banks and transfusion practices as the sector is largely fragmented with uneven distribution of blood banks and supply of blood in parts of the country. Donors are usually provided with refreshments after the procedure, which include glucose drinks, biscuits and fruits. Some organisations offer transportation facilities, as well as certificates or badges as gratitude.
