How many blood types are there in the ABO/RH blood group?
Doctors need to take into account both ABO and Rh when considering blood types. This means there are eight main blood types in the ABO/Rh blood group system. Some are more common than others.
What are the two types of antigens?
Scientists use two types of antigens to classify blood types: 1 ABO antigens 2 Rh antigens
What is the ABO system?
The ABO blood group system classifies blood types according to the different types of antigens in the red blood cells and antibodies in the plasma. They use the ABO system alongside the RhD antigen status to determine which blood type or types will match for a safe red blood cell transfusion. There are four ABO groups:
Which blood cells carry oxygen?
red blood cells , which carry oxygen around the body. white blood cells, which play a crucial role in the immune system. plasma, which is a yellowish liquid that contains proteins and salts. platelets, which enable clotting. The blood group will depend on which antigens are on the surface of the red blood cells.
What happens if you give someone the wrong blood type?

Is AB negative the rarest blood type?
O positive is the most common, and AB negative is the rarest. If a person needs a blood transfusion, their blood type must be compatible with that of the donor to avoid complications. Blood donations save lives every day, but receiving the wrong type of blood can lead to life-threatening consequences.
What is the blood type?
A blood type (also known as a blood group) 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.
What are the two most important blood groups?
The two most important blood group systems are ABO and Rh ; they determine someone's blood type (A, B, AB, and O, with +, − or null denoting RhD status) for suitability in blood transfusion .
What are the two antigens in the blood?
The ABO blood group system involves two antigens and two antibodies found in human blood. The two antigens are antigen A and antigen B. The two antibodies are antibody A and antibody B. The antigens are present on the red blood cells and the antibodies in the serum. Regarding the antigen property of the blood all human beings can be classified into 4 groups, those with antigen A (group A), those with antigen B (group B), those with both antigen A and B (group AB) and those with neither antigen (group O). The antibodies present together with the antigens are found as follows: 1 Antigen A with antibody B 2 Antigen B with antibody A 3 Antigen AB has no antibodies 4 Antigen nil (group O) with antibody A and B.
Who discovered the blood type?
Blood types were first discovered by an Austrian physician, Karl Landsteiner, working at the Pathological-Anatomical Institute of the University of Vienna (now Medical University of Vienna ). In 1900, he found that blood sera from different persons would clump together (agglutinate) when mixed in test tubes, and not only that, some human blood also agglutinated with animal blood. He wrote a two-sentence footnote:
Can you donate blood to a group other than AB?
Therefore, an individual with type AB blood can receive blood from any group (with AB being preferable), but cannot donate blood to any group other than AB. They are known as universal recipients.

Is ABO blood type predictive?
A popular pseudoscientific belief in Japan (known as " ketsueki-gata ") (血液型) and South Korea is that a person's ABO blood type is predictive of their personality, character, and compatibility with others. Researchers have established no scientific basis exists for blood type personality categorization, and studies have found no "significant relationship between personality and blood type, rendering the theory "obsolete" and concluding that no basis exists to assume that personality is anything more than randomly associated with blood type."
Overview
Blood group systems
- The ABO gene is connected with brain function and memory loss. People who have blood types A, B, and AB are up to 82 percent more likely to develop cognition and memory problems — which can lead to dementia — compared to those with Type O. One possible reason for this memory loss is the fact that blood type can lead to things like high blood pressu...
Clinical significance
Blood typing
A blood type (also known as a blood group) 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(or …
History
A complete blood type would describe each of the 43 blood groups, and an individual's blood type is one of many possible combinations of blood-group antigens. Almost always, an individual has the same blood group for life, but very rarely an individual's blood type changes through addition or suppression of an antigen in infection, malignancy, or autoimmune disease. Another more common cause of blood type change is a bone marrow transplant. Bone-marrow transplants are …
Society and culture
Transfusion medicine is a specialized branch of hematology that is concerned with the study of blood groups, along with the work of a blood bank to provide a transfusion service for blood and other blood products. Across the world, blood products must be prescribed by a medical doctor (licensed physician or surgeon) in a similar way as medicines.
Much of the routine work of a blood bankinvolves testing blood from both donors and recipients …

Typically, blood type tests are performed through addition of a blood sample to a solution containing antibodies corresponding to each antigen. The presence of an antigen on the surface of the blood cells is indicated by agglutination. In these tests, rather than agglutination, a positive result is indicated by decolorization as red blood cells which bind to the nanoparticles are pulled toward a magnet and removed from solution.
