Introduction The Rh blood group system, second only to ABO in importance, classifies people based on antigens on their red blood cells. The most crucial antigen in this group is, RhD, which commonly determines the Rh positive or Rh negative blood type. If a person is...
Transfusion Medicine
Interpretation of Antibody Identification Antigram
Antigen identification antigrams decode antibody reactions in blood transfusions, ensuring safe blood selection by identifying compatible red blood cells that lack the antigen targeted by the recipient’s antibody.
Antibody Identification
Incubate patient serum with panel RBCs, check for agglutination! Enzymes & antiglobulin tests may be used to reveal hidden antibody reactions.

Interpretation of Antibody Identification Antigram
Antigen identification antigrams decode antibody reactions in blood transfusions, ensuring safe blood selection by identifying compatible red blood cells that lack the antigen targeted by the recipient’s antibody.
Serologic Crossmatch
Crossmatching mimics transfusion by mixing recipient serum & donor cells. Clumping (agglutination) indicates incompatibility, preventing transfusion reactions.
Antibody Screening
Antibody screening mixes patient plasma with red blood cells to detect unexpected antibodies. Agglutination indicates possible antibodies, requiring further identification for safe blood transfusions
Serologic Crossmatch
Crossmatching mimics transfusion by mixing recipient serum & donor cells. Clumping (agglutination) indicates incompatibility, preventing transfusion reactions.
Indirect Antiglobulin (Coombs) Test (IAT)
Unmask hidden blood threats! IAT protocol detects antibodies in serum, ensuring safe transfusions & diagnosing immune disorders.
Direct Antiglobulin (Coombs) Test (DAT)
To detect the presence of antibodies or complement proteins bound to red blood cells (RBCs) in vivo, indicating potential immune-mediated hemolysis.
Rh Typing using Tube Method
Unraveling the Rh code! Mix blood with anti-sera in tubes. Incubate, centrifuge, & observe. Clumping reveals antigen presence, guiding safe transfusions.
ABO RhD Test Tube Method
The ABO RhD Blood Grouping Tube Method is a serological technique used to determine an individual’s blood type by mixing blood serum and red blood cells with antisera and observing for agglutination.
