Rh Blood Group System
Key Takeaways The Rh blood group system is a classification of blood types based on the presence or absence of certain proteins (antigens) on the surface of red blood cells. Rh incompatibility can lead to serious complications. Antigen System: Rh antigens on red blood...
Serologic Crossmatching (Blood Compatibility Test)
Cross-matching mimics transfusion by mixing recipient serum & donor cells. Clumping (agglutination) indicates incompatibility, preventing transfusion reactions.
Indirect Antiglobulin (Coombs) Test (IAT)
Indirect Coombs test (IAT) procedure 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 (Blood Group Typing) 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.
ABO Blood Group System
The ABO blood group system is a classification of human blood based on the presence or absence of A and B antigens on red blood cells.
