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.
Blood plasma is a light amber-colored liquid component of blood in which blood cells are absent, but which contains proteins and other constituents of whole blood in suspension. It makes up about 55% of the body's total blood volume. It is the intravascular part of extracellular fluid. It is mostly water, and contains important dissolved proteins, glucose, clotting factors, electrolytes, hormones, carbon dioxide, and oxygen. It plays a vital role in an intravascular osmotic effect that keeps electrolyte concentration balanced and protects the body from infection and other blood-related disorders.
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. 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.
In immunology, antiserum is a blood serum containing antibodies that is used to spread passive immunity to many diseases via blood donation (plasmapheresis). For example, convalescent serum, passive antibody transfusion from a previous human survivor, used to be the only known effective treatment for ebola infection with a high success rate of 7 out of 8 patients surviving.
Apheresis is a medical technology in which the blood of a person is passed through an apparatus that separates out one particular constituent and returns the remainder to the circulation. It is thus an extracorporeal therapy.
Plasmapheresis is the removal, treatment, and return or exchange of blood plasma or components thereof from and to the blood circulation. It is thus an extracorporeal therapy, a medical procedure performed outside the body.
CSL Limited is an Australian multinational specialty biotechnology company that researches, develops, manufactures, and markets products to treat and prevent serious human medical conditions. CSL's product areas include blood plasma derivatives, vaccines, antivenom, and cell culture reagents used in various medical and genetic research and manufacturing applications. The company was established in 1916 as Commonwealth Serum Laboratories and was wholly owned by the Australian federal government until its privatisation in 1994.
Plateletpheresis is the process of collecting thrombocytes, more commonly called platelets, a component of blood involved in blood clotting. The term specifically refers to the method of collecting the platelets, which is performed by a device used in blood donation that separates the platelets and returns other portions of the blood to the donor. Platelet transfusion can be a life-saving procedure in preventing or treating serious complications from bleeding and hemorrhage in patients who have disorders manifesting as thrombocytopenia or platelet dysfunction. This process may also be used therapeutically to treat disorders resulting in extraordinarily high platelet counts such as essential thrombocytosis.
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.
Rho(D) immune globulin (RhIG) is a medication used to prevent RhD isoimmunization in mothers who are RhD negative and to treat idiopathic thrombocytopenic purpura (ITP) in people who are Rh positive. It is often given both during and following pregnancy. It may also be used when RhD-negative people are given RhD-positive blood. It is given by injection into muscle or a vein. A single dose lasts 12 weeks. It is made from human blood plasma.
Prothrombin complex concentrate (PCC), also known as factor IX complex, sold under the brand name Kcentra among others, is a combination medication made up of blood clotting factors II, IX, and X. Some versions also contain factor VII. It is used to treat and prevent bleeding in hemophilia B if pure factor IX is not available. It may also be used for reversal of warfarin therapy. It is given by slow injection into a vein.
CSL Behring is a biopharmaceutical company, manufacturing plasma-derived, and recombination therapeutic products. The company is a combination of Behringwerke, founded in 1904 in Marburg, Germany by Emil von Behring, and the Commonwealth Serum Laboratories (CSL), established in Australia in 1916 to provide vaccines to the people of Australia, as well as other companies acquired since 2004.
The New Zealand Blood Service is the provider of blood services for New Zealand. The service is a Crown entity responsible to New Zealand's Parliament and is governed by a Board appointed by the Minister of Health.
Grifols, S.A. is a Spanish multinational pharmaceutical and chemical manufacturer. Principally a producer of blood plasma–based products, a field in which it is the European leader and largest worldwide, the company also supplies devices, instruments, and reagents for clinical testing laboratories.
The Gift of Life Marrow Registry is a non-profit organization founded in 1991 and headquartered in Boca Raton, Florida that operates a public bone marrow and blood stem cell registry while facilitating transplants for children and adults suffering from life-threatening illnesses, including leukemia, lymphoma, other cancers and genetic diseases.
In the 1970s and 1980s, a large number of people – most of whom had haemophilia – were infected with hepatitis C and HIV, the virus that leads to acquired immune deficiency syndrome (AIDS), as a result of receiving contaminated clotting factor products. In England, these were supplied by NHS England. Many of the products were imported from the US.
The South African National Blood Service (SANBS) is a non-profit organisation that provides human blood for transfusion that operates in South Africa, with the exception of the Western Cape, which has its own blood service. The head office of the SANBS is in Constantia Kloof, Gauteng, near Johannesburg, but there are blood collection operations in eight of the nine provinces. Western Cape has a separate blood centre, the Western Cape Blood Service. SANBS was founded in 2001 from a merger of seven blood centres, and was embroiled in controversy in 2004 over a policy of racial profiling for blood safety.
Blood donation in Bangladesh is an activity conducted by several different organisations. As of 2011, about 25% of the nation's blood supply came from voluntary donation, 20–25% from paid donors, and 50–55% from one-time donation for a specific patient.
Immunoglobulin therapy is the use of a mixture of antibodies to treat several health conditions. These conditions include primary immunodeficiency, immune thrombocytopenic purpura, chronic inflammatory demyelinating polyneuropathy, Kawasaki disease, certain cases of HIV/AIDS and measles, Guillain–Barré syndrome, and certain other infections when a more specific immunoglobulin is not available. Depending on the formulation it can be given by injection into muscle, a vein, or under the skin. The effects last a few weeks.
Canadian Plasma Resources (CPR) is a private, for-profit bio-pharmaceutical company and a licensed blood establishment based in Saskatoon, Saskatchewan, Canada.
