the Comparative Coagulation Laboratory of the Animal Health Diagnostic Center at Cornell University, the Equine Blood Testing Laboratory in Kentucky, the Stormont Laboratory in California). induce a hemolytic reaction) can cause agglutination and/or hemolysis of red cells.īlood typing (for the most common blood groups) is offered by a few specialized veterinary diagnostic laboratories (e.g. The most common route of exposure is from previous blood transfusions, however there are less obvious sources of exposure, such as vaccinations that contain foreign red blood cell antigens. Acquired antibodies are produced after exposure to an incompatible blood type, which is from exposure to blood or products containing erythrocytes or their antigens. some will not produce a transfusion reaction. Naturally occurring antibodies occur in most species and vary in their pathological significance, i.e. There are two types of antibodies to blood group antigens naturally occurring antibodies and antibodies acquired after exposure to the blood group antigen. Knowledge of blood types in the different species is important as transfusion of incompatible blood (the donor animal has a different blood type from the recipient animal) can result in severe hemolytic transfusion reactions and even death, in some instances. In humans, there is the ABO system of blood types, whereas animals have a variety of different blood types. Blood Pressure Explained Brewer's: Health Check Your Healthy Heart I.Q.Blood types (or groups) are determined by specific antigens found on the surface of erythrocytes. Or, if you're interested in other health subjects, you might be interested in our list of the top air purifiers. Many blood donation centers are run by the Red Cross. The American Association of Blood Banks maintains a database of locations for individuals to donate blood. According to the Centers for Disease Control, there are more than 9.5 million blood donors in the United States and an estimated 5 million patients who receive blood annually, resulting in a total of 14.6 million transfusions per year. Conversely, AB are rare blood types AB negative is the rarest.ĭonor blood is tested for HIV, hepatitis, syphilis, West Nile virus and other diseases before transfusion. Type O blood won't provoke a response from anti-a or anti-b antibodies. Luckily for the patients, group O is the most common blood type among the U.S. If someone receives the wrong blood, their immune system will kick in and produce antibodies to attack the new red cells. Matching the right types of blood is very important. Aside from transferring blood as a whole, parts of blood, such as red blood cells, platelets or plasma can also be transferred to individuals. Blood that is lost through an injury, an illness or a surgery can be replaced through transfusion. In Japan, the idea of blood type as personality type is so popular that Japanese ask "What's your blood type?" about as often as Americans ask "What's your sign?"Ī blood transfusion is the transfer of blood from one person to another.Legend has it that Type A is calm and trustworthy Type B is creative and excitable Type AB blood is thoughtful and emotional and Type O is a confident leader. Some people think blood type tells about personality.Dogs have 4 blood types cats have 11 cows have about 800. Different kinds of animals have different kinds of blood.In China, over 99 percent of the population has Rh+ blood. Certain blood types are more common in certain countries.Blood type is inherited, just like eye color. Individuals with Type AB positive blood are considered the universal recipients because people with that type can receive any blood type.īlood Type Chart: Below is a chart listing blood types, the percentage of Americans with that type, and the types they can donate to. People with Type O negative blood are considered to be universal donors because they can donate to people of any blood type. If the blood types are not compatible, red blood cells will clump together, making clots that can block blood vessels and cause death. During a blood transfusion, a patient must receive a blood type that is compatible with his or her own. Knowing a person's exact blood type is critical when a blood transfusion is necessary. The name Rhesus comes from Rhesus monkeys, in which the protein was first discovered. Rhesus refers to another type of antigen, or protein, on the surface of red blood cells. Blood is either Rh positive (Rh+) or Rh negative (Rh-). The Rh FactorĮach blood type is also grouped by its Rhesus factor, or Rh factor. For example, the surface of red blood cells in Type A blood has antigens known as A-antigens. Each letter refers to a kind of antigen, or protein, on the surface of red blood cells. Human blood is grouped into four types: A, B, AB, and O.
