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.
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 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. 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.
AABB is an international, not-for-profit organization representing individuals and institutions involved in the field of transfusion medicine and biotherapies.
Serology is the scientific study of serum and other body fluids. In practice, the term usually refers to the diagnostic identification of antibodies in the serum. Such antibodies are typically formed in response to an infection, against other foreign proteins, or to one's own proteins. In either case, the procedure is simple.

The I-35W Mississippi River bridge was an eight-lane, steel truss arch bridge that carried Interstate 35W across the Mississippi River one-half mile downstream from the Saint Anthony Falls in Minneapolis, Minnesota, United States. The bridge opened in 1967, and was Minnesota's third busiest, carrying 140,000 vehicles daily. After only 39 years in service, it experienced a catastrophic failure during the evening rush hour on August 1, 2007, killing 13 people and injuring 145. The National Transportation Safety Board (NTSB) cited a design flaw as the likely cause of the collapse, noting that an excessively thin gusset plate ripped along a line of rivets. Additional weight on the bridge at the time of failure was also cited by the NTSB as a contributing factor.
The New York Blood Center (NYBC) is a community, nonprofit blood bank based in New York City. Established in 1964 by Dr. Aaron Kellner, NYBC supplies blood to approximately 200 hospitals in the Northeast United States. NYBC and its operating divisions also provide transfusion-related medical services to over 500 hospitals nationally.
A medical laboratory or clinical laboratory is a laboratory where tests are conducted out on clinical specimens to obtain information about the health of a patient to aid in diagnosis, treatment, and prevention of disease. Clinical medical laboratories are an example of applied science, as opposed to research laboratories that focus on basic science, such as found in some academic institutions.
Many countries have laws, regulations, or recommendations that effectively prohibit donations of blood or tissue for organ and corneal transplants from men who have sex with men (MSM), a classification irrespective of their sexual activities with same-sex partners and of whether they identify themselves as bisexual or gay. Temporary restrictions are sometimes called "deferrals", since blood donors who are found ineligible may be found eligible at a later date. However, many deferrals are indefinite meaning that donations are not accepted at any point in the future, constituting a de facto ban. Even men who have monogamous relations with their same-sex partners are found ineligible.
A transfusion transmitted infection (TTI) is a virus, parasite, or other potential pathogen that can be transmitted in donated blood through a transfusion to a recipient. The term is usually limited to known pathogens, but also sometimes includes agents such as simian foamy virus which are not known to cause disease.
Carter BloodCare is a 501(c)(3) nonprofit organization headquartered in Bedford, Texas. Carter BloodCare currently provides more than 440,000 blood products annually to over 200 hospitals serving patients in more than 50 counties across North, Central and East Texas. One of the largest blood centers in operation in the United States, Carter BloodCare’s mission is “we save lives by making transfusion possible.”.
Dr. Jai Gopal Jolly, famously known as Dr. J. G. Jolly was an Indian physician and professor of the Department of Transfusion Medicine at the Post Graduate Institute of Medical Education and Research, Chandigarh, India. He is an internationally known expert in the field of blood transfusion, who pioneered the voluntary blood donation movement in India, and is regarded as the "Father of Transfusion Medicine in India". He spearheaded the campaign to prohibit sale and purchase of blood from professional donors in India, which was later incorporated into the National Blood Policy of India by the Government of India. He has generated awareness among the masses about the significance of blood donation programmes by observing "Blood Donation Day" on 1 October. This has helped in obtaining adequate quantity of quality blood from voluntary donors.
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.
The West Bengal blood test scam was an instance in which an Indian company, Monozyme India, sold thousands of defective blood test kits to various medical facilities in the Indian State of West Bengal. The resulting increase in cases of infectious diseases led to a government probe, the arrest of several prominent directors of Monozyme India, and widespread criticism being levied against the healthcare system of West Bengal.
