Compatibility testing, infectious disease screening, and adherence to regulations.

Who discovered the Rh blood group system?

Karl Landsteiner and Alexander Wiener discovered the Rh blood group system in 1940.

What constitutes a blood component therapy?

Transfusing specific blood components instead of whole blood to ensure patients receive only what they need.

During blood typing, what is assessed in forward typing?

The presence of A and B antigens on the surface of red blood cells.

What is a common reason for allergic transfusion reactions?

Recipient allergy to donor plasma proteins.

What are the two major types of hemolytic disease of the fetus and newborn (HDFN)?

RhD-related HDFN and ABO HDFN.

What is the purpose of RhoGAM?

It is administered to Rh-negative mothers to prevent the formation of anti-D antibodies.

How long can platelets be stored during transfusion?

Platelets must be stored at room temperature (20 - 24℃) with agitation for up to 5 days.

What test is essential for compatibility testing before transfusion?

Crossmatching, which checks for compatibility between donor red blood cells and recipient plasma.

What are the symptoms of Acute Hemolytic Transfusion Reaction (AHTR)?

Symptoms include fever, chills, back pain, hemoglobinuria, hypotension, and DIC.

What laboratory finding strongly suggests hemolysis during an acute hemolytic transfusion reaction?

Decreased haptoglobin.

What is the main antibody affecting pregnancy in Hemolytic Disease of the Fetus and Newborn (HDFN)?

Anti-D antibodies are the most common cause of HDFN.

What is the purpose of blood typing?

To determine the blood group of a person to ensure safe blood transfusions.

What are the key components of transfusion safety protocols?

Verification of donor information, recipient identification, and crossmatching tests.

What is the common cause of delayed hemolytic transfusion reactions?

The anamnestic response to previously encountered red blood cell antigens.

What role do blood banks play in transfusion medicine?

They are responsible for the collection, testing, and distribution of blood products.

What is Massive Transfusion Protocol (MTP)?

A set of guidelines for managing patients who require large volumes of blood transfusion.

What is the role of the immune response in immunohematology?

The immune response involves the formation of antibodies against blood group antigens during transfusions.

What regulatory body oversees blood donation and transfusion practices in the U.S.?

The Food and Drug Administration (FDA) oversees blood donation and transfusion practices in the U.S.

What is the purpose of infectious disease screening in blood donations?

To ensure the safety of the blood supply by preventing the transmission of infections from donor to recipient.

What is the significance of antigen-antibody compatibility?

Antigen-antibody compatibility is crucial to prevent transfusion reactions that can be harmful or fatal.

How does hemolytic disease of the fetus and newborn (HDFN) occur?

HDFN occurs when maternal antibodies cross the placenta and attack fetal red blood cells.
