• What is the primary purpose of blood banking?
• Prevent anemia
• Ensure safe transfusion of blood products
• Diagnose hematologic disorders 2 / 4

• Treat autoimmune diseases

Ensuring safe transfusion is the cornerstone of blood banking practices.

• Which blood component contains the highest concentration of

coagulation factors?

• Packed red blood cells
• Platelets
• Fresh frozen plasma
• Cryoprecipitate

Fresh frozen plasma is rich in all coagulation factors.

3. The ABO blood group system is based on:

• The presence or absence of A and B antigens on red blood cells
• Rh factor only
• Antibody types in plasma
• HLA typing

The ABO system classifies blood by A and B antigens on the RBC surface.

• What is the most immunogenic blood group antigen after ABO?
• Kell
• Duffy
• Rh(D) 3 / 4

• Kidd

Rh(D) is second only to ABO in immunogenicity.

5. The DAT (Direct Antiglobulin Test) detects:

• Free antibodies in the serum
• Antibodies or complement attached to RBCs in vivo
• Hemoglobin levels
• Platelet count

DAT identifies in vivo coating of RBCs, often indicating autoimmune hemolysis.

6. The indirect antiglobulin test is used for:

• Detecting antigens on donor RBCs
• Detecting antibodies in the recipient’s serum
• Measuring hematocrit
• Crossmatching donor platelets

IAT detects unexpected antibodies before transfusion.

• What type of antibodies are naturally occurring in the ABO system?
• IgG
• IgM
• IgA
• IgE

ABO antibodies are typically IgM, reacting at room temperature.
