AMT MLS Domain 6: Immunohematology Welcome to your AMT MLS Domain 6: Immunohematology 1. AMT MLS: Immunohematology In the context of immunohematology, what is the primary significance of the Duffy blood group system? It is the main determinant of the ABO blood group. It affects susceptibility to Plasmodium vivax malaria. It determines the Rh factor positivity or negativity. It is crucial for platelet compatibility. None 2. AMT MLS: Immunohematology When performing a crossmatch test, which phase is most critical for detecting antibodies against high-frequency antigens? Immediate spin phase Antiglobulin phase Saline phase Albumin phase None 3. AMT MLS: Immunohematology What is the primary role of the indirect antiglobulin test (IAT) in blood bank testing? Detection of ABO incompatibilities Identification of unexpected antibodies in the patient's serum Determination of hemoglobin levels Measurement of clotting factors None 4. AMT MLS: Immunohematology Which antigen is associated with the Kell blood group system and is significant for its immunogenicity? K Jka Fya M None 5. AMT MLS: Immunohematology In immunohematology, what is the significance of detecting a positive Direct Antiglobulin Test (DAT)? It confirms the presence of anti-A or anti-B antibodies on the red cell surface. It indicates compatibility between donor and recipient blood. It signifies that there are antibodies or complement bound to the patient's red cells. It determines the blood group of an individual. None 6. AMT MLS: Immunohematology What is the purpose of the elution procedure in immunohematology? To remove antibodies from the patient's plasma To concentrate red blood cells for transfusion To detach and identify antibodies bound to red blood cells To confirm the ABO blood grouping None 7. AMT MLS: Immunohematology When considering Rh compatibility, which scenario is most likely to lead to hemolytic disease of the newborn (HDN)? Rh-negative mother and Rh-negative fetus Rh-positive mother and Rh-negative fetus Rh-negative mother and Rh-positive fetus Rh-positive mother and Rh-positive fetus None 8. AMT MLS: Immunohematology In transfusion medicine, what is the primary concern when a patient has an antibody against the 'e' antigen of the Rh system? Difficulty in finding compatible blood, as 'e' is a high-frequency antigen. Immediate hemolytic transfusion reaction. No significant concern, as the 'e' antigen is not clinically significant. Risk of graft-versus-host disease. None 9. AMT MLS: Immunohematology What is the primary reason for performing a serum-to-cell ratio study in immunohematology? To determine the optimal ratio for antibody detection To identify the ABO blood type To assess the potency of an anticoagulant To evaluate the efficiency of platelet transfusion None 10. AMT MLS: Immunohematology Why is it important to test for the presence of the S and s antigens during pre-transfusion testing? They are associated with immediate transfusion reactions. They are involved in the rapid clearance of transfused platelets. They can lead to delayed hemolytic transfusion reactions. They determine the plasma volume required for transfusion.
