How does antigens and antibodies determine one's abo blood type?

What is the difference between blood types?

The red blood cells define the blood group you actually belong to. There are small markers known as antigens on the red cells surface, but they are so tiny that it cannot be viewed under a microscope. However, every person has different antigens but for identical twins. The antigens identify the blood types and are the key to match the transfusions as well that helps in avoiding serious complications. The blood group structure is defined as the ABO system. Another significant factor worth considering is the Rh system. All the blood groups have the possibility of having Rh antigens. Conversely, there are some who have it, while some do not have it. In case, the blood group belongs to Rh antigens, then they are Rh positive and a person having A blood group with Rh positive is recognized as A+. In case a person has A blood group with Rh negative, then it is A-. This is the same pattern followed for O, B or AB blood group as well. The Rh system duals the blood groups effectively so that the positive blood type does not get mixed with negative.

What is a non pathogen antigen?

Antigens are substances that incite your immune system to respond by producing antibodies. They include both foreign substances, such as pollen, and substances made by the body. Ones made by the body are non harmful.

Which part of the blood does blood type refer to?

Blood types (ABO, Rhesus, etc.) refer to the different types of antigens on the cell surface of red blood cells (primarily, since usually only RBCs are transfused). Antigens are either sugars, proteins, glycoproteins, etc. that exist on the surface cells that enable cells to be recognized by the immune system using antibodies.

Can b donate to a?

no because the antibodies in type A blood differ from the ones in type B blood so it would recognize the different blood as a threat and eliminate it

How is it that an incompatible ABO blood group will generate a transfusion reaction the first time a transfusion is given while Rh incompatibility creates a problem the second time?

The antigens of the ABO system are mimicked by bacterial cell walls. So if your body does not actively suppress antibodies to them (because you have them) then antibodies will form over time to the ones you so not have (A or B or both). The rhesus factor (Rh) is not mimicked in nature and so antibodies are not formed in Rh negative people until after an exposure - usually when an Rh negative women carries an Rh positive child. If the person is Rh positive then antibodies will not form no matter what.

What are white blood cells made up of?

White blood cells are made up of monocytes, lymphocytes, neutrophils, basophils, and eosinophils. White blood cells are the immunity cells, as they are always fighting invaders that threaten the body's health.

What does reactive HBs antigen mean?

HBs antigen is an acronym for Hepatits B like antigens found in the blood cells They are the ones that assist the body to respond to any foreign antibody pertaining to that antigen.

Why must be matched before a blood transfusion?

red blood cells have protein embedded in their membranes. people make antibodies against these proteins - except the ones they already have. thus, a doners and a recipients blood "type" must match. There's more ... but it'll start you off.

What is blood group and their importance in human?

Blood groups are a classification of the blood in a body that is based on the presence or absence of inherited antigenic substances on the surface of red blood cells. These antigens can come in a number of forms, namely carbohydrates, proteins, glycoproteins and glycolipids. The ones that are there depend on the blood group system. These red blood cell surface antigens can stem from one allele and together they form a blood group system. A person's blood group is inherited from their parents and represent contributions from both the mother and the father. The International Society of Blood Transfusion have classified a total of 30 human blood groups. It is important to have blood groups, in a medical sense, to aid successful blood transfusions. Certain people with certain blood groups can only accept blood from the same system, others have blood groups that can be accepted by most humans. Classifying blood allows hospitals to keep a supply of each group from donors ready for any transfusions that may need it. Blood donors are a crucial part to this system and although thousands of people donate blood, there is still a short supply of some of the rarer groups. Blood group systems are categorized by two sub systems. These are the ABO blood group system and the Rh blood group system. The ABO blood group system is the most important blood group system regarding human blood transfusion. The associated anti A and anti B antibodies are usually Immunoglobin M. These antibodies are produced in the first few years of life be sensitization to a variety of foods, bacteria and viruses. The Rh blood group system is the second most important blood group system for human blood transfusion. The most prominent antigen is the D antigen as it is the most likely to provoke an immune system response from the other five antigens.

How do you produce immunity after a vaccine?

a vaccine is dead or weakened form of the virus you want to get immunity for. After the white blood cells fight them off, they already have the necessary antibodies to fight off stronger ones to come.

What is ANA Screen test?

ANA stands for antinuclear antibodies. About 10 million Americans have them. Many have no disease. The older you are, the more likely you are to have a positive ANA. The ANA test is a titer. The result is the number of times ones blood must be diluted in order to come up with a sample that has no autoantibodies. The autoantibodies are then tested with immunofluorescence. The resulting pattern helps determine the type of disease.
