Blood Screening Market

As the number of people suffering from diseases and the volume of surgical procedures is rising, the need for blood donors and blood screening is growing as well. When it comes to blood transfusion, the safety of the blood and its components is of the utmost priority, and it is…

Blood Group Systems

International Society of Blood Transfusion (ISBT) Working Party has organized red cell antigens into 25 blood group systems. Red cell antigens that are produced by alleles (alternative forms of a specified gene) at a single gene locus or very closely linked loci constitute a blood group system.

Preparation of Blood Components From Whole Blood for Transfusion

A single whole blood donation can be separated into different components to provide treatment to more than one patient. One unit of whole blood can be broken down into one unit of packed red cells, one unit of platelets, and one unit of fresh frozen plasma/cryoprecipitate. This practice avoids wastage…

ABO GROUPING AND Rh D GROUPING

ABO Grouping There are two methods for ABO grouping: Cell grouping (forward grouping): Red cells are tested for the presence of A and B antigens employing known specific anti-A and anti-B (and sometimes anti-A, B) sera. Serum grouping (reverse grouping): Serum is tested for the presence of anti-A and anti-B…

FALSE REACTION IN ABO GROUPING

Autoagglutination: Presence of IgM autoantibodies reactive at room temperature in patient’s serum can lead to autoagglutination. If autocontrol is not used, blood group in such a case will be wrongly typed as AB. Therefore, for correct result, if autocontrol is also showing agglutination, cell grouping should be repeated after washing…

Rh D GROUPING METHOD

D antigen is the most immunogenic after ABO antigens and therefore red cells are routinely tested for D. Individuals are called as Rh-positive or Rh-negative depending on presence or absence of D antigen on their red cells. Following transfusion of Rhpositive blood to Rh-negative persons, 70% of them will develop…

Microplate Technique for Rh D Grouping

Microplate is a polystyrene plate consisting of 96 micro wells of either U- or V-shape. Grouping is carried out in micro wells. This method is sensitive and ideal for large number of samples (see Figure 787.1).   Further reading: Rh D GROUPING METHOD

DETERMINATION OF BLOOD GROUP BY SLIDE METHOD

Principle Red cells from the specimen are reacted with reagent antisera (anti-A and anti-B). Agglutination of red cells indicates presence of corresponding antigen (agglutinogen) on red cells. Specimen Capillary blood from finger prick, or venous blood collected in EDTA anticoagulant. Reagents ABO antisera: See box 786.1 and Figure 786.1. Box…

DETERMINATION OF BLOOD GROUP BY TUBE METHOD

Test tube method is more reliable than slide test, but takes longer time and more equipment. For cell grouping, patient’s saline-washed red cells are mixed with known antiserum in a test tube; the mixture is incubated at room temperature, and centrifuged. For serum grouping, patient’s serum is mixed with reagent…

Cross Match Procedure in Blood Bank (Manual Method)

When the recipient’s ABO and Rh blood groups are determined, the donor blood unit that is ABO and Rh compatible is selected, and compatibility test is carried out. The purpose of compatibility test is to prevent the transfusion of incompatible red cell units and thus avoidance of hemolytic transfusion reaction…
