abo blood group test

A: The presence of Antigen A; B: The presence of Antigen B; AB blood group: Presence of both Antigens A and B; Blood group O: Absence of both Antigens That's because type O negative blood cells don't have antibodies to A, B or Rh antigens. This system is used because antibodies needed for testing are consistent and naturally present in the serum of those blood types. Not all people have the same blood group as there are many different types, of which some are more commonly found than others. By doing a series of such tests it is possible to determine what antigens are on your red blood cells and therefore determine your blood group. WebMD does not provide medical advice, diagnosis or treatment. Your blood sample is mixed with antibodies against type A and B blood. There are various types of red blood cell antigens - the ABO and rhesus types are the most important. ABO Blood Grouping Test Procedure The ABO blood group of a person depends on whether his red blood cells contain one, both, or neither of the 2 blood group antigens A and B, and therefore the human blood groups are differentiated as type A, type B, type AB, or O as mentioned earlier. Most people have about 4-6 liters of blood. Blood Group Test - More Information.

ABO grouping is a test performed to determine an individual's blood type. It is cross check for forward typing. Test your understanding of different blood types and the blood group system using an interactive quiz/printable worksheet combo. If the blood reacts to the Rh test with agglutinating, it is called Rh positive and if it doesn't, it is Rh Negative. Principle: This ABO grouping test is based on the principle of haemagglutination reaction. The ABO blood group shows if the red blood cells have A and B antigens. Therefore, before a blood transfusion is done, a donor bag of blood is selected with the same ABO and rhesus blood group as yourself. Your blood group depends on which antigens occur on the surface of your red blood cells. Blood is classified into different blood groups depending on the presence of certain substances.

Reverse blood grouping is a procedure to confirm ABO blood group based on the presence or absence of anti-A and anti-B in serum using known A and B red cells. These tests include ABO and RhD blood groups, a blood group antibody screen and a crossmatch. Within the ABO group, four major categories are divided into eight common blood types: A, B, O, and AB. If blood cells stick together, it means the blood reacted with one of the antibodies. These tests include ABO and RhD blood groups, a blood group antibody screen and a crossmatch.
