Methods of blood grouping: 1 Slide method 2 Tube method 6. Tube method — better method but takes longer Sample in tube with antiserum incubate it centrifuge it examine it macroscopically and microscopically for agglutination. Universal donor — blood group O as no Ag so no agglutination. Universal recepient — blood group AB as both A and B Ags present so agglutination occurs in both as no Abs present in serum.

Rh negative: There is absence of D antigen. Cc and Ee antigen: These are weak antigens and therefore risk of sensitisation is less than that of D antigen. You just clipped your first slide!

What is the difference between a group and save and a crossmatch?

Pune, Sept. Anemia is the deficiency of healthy red blood cells RBCs in the body, which leads to lack of oxygen supply to the organs. As a result, anemic people need to undergo regular blood transfusion exercises to maintain a stable RBC count in the body. Thus, growing incidence of anemia and the subsequent rising demand for blood transfusion will lead the blood group typing market trends in the foreseeable future. The report on this market states that the market value stood at USD 1.

This is a set of tests that looks for harmful interactions between your blood and donor blood. The tests are done before a blood transfusion. Blood typing is the first step. Your blood is also tested to find out if your Rh type is negative or positive. It's important for your healthcare provider to know your blood type in order to select a donor blood that's compatible before doing the crossmatch.


Red cell antigens i.e. 'blood grouping'. • Antibody/ies in the plasma i.e. 'antibody screening', antibody identification. • An incompatible crossmatch.


Blood groups systems

International Society of Blood Transfusion has recently recognized 33 blood group systems. Apart from ABO and Rhesus system, many other types of antigens have been noticed on the red cell membranes. Blood grouping and cross-matching is one of the few important tests that the anaesthesiologist orders during perioperative period. Hence, a proper understanding of the blood group system, their clinical significance, typing and cross-matching tests, and current perspective are of paramount importance to prevent transfusion-related complications. Nonetheless, the knowledge on blood group system is necessary to approach blood group-linked diseases which are still at the stage of research.

    Cross Matching is a procedure performed prior to a blood transfusion to determine whether donor blood is compatible or incompatible with recipient blood.

    The crossmatch will detect the following: • 1. Most recipient antibodies directed against antigens on the donor red blood cells. 2. Major errors in ABO grouping.

    Cross-matching or crossmatching is a test performed before a blood transfusion as part of blood compatibility testing.
