What is reverse typing?

• Patient serum + known red cells

• Patient cells + known antibodies

• Patient serum + donor cells

• Patient cells + donor serum

Which blood group is considered the universal donor?

• Group AB

• Group B

• Group A

• Group O

What is the recommended method for ABO grouping?

• Tube technique

• Slide test

• Microplate

• Test Tube Method

What is the procedure for cross-matching in blood transfusion?

• Add two drops of anti A, anti B, anti D in three different tubes

• Prepare 2-5% suspension of test sample in normal saline

• Add one drop of cell suspension (A cell to A tube, B cell to B tube and one drop of O cell to O tube

• Place 2 drops of recipient's serum and add washed donor red cell suspension

What is the advantage of the tube method in ABO typing?

• It can be used during camps

• It is highly sensitive

• It is a routine test

• Allows longer incubation of antigen and antibody mixture without drying

What is the role of antigens in blood grouping?

• To determine the antigen expressed

• To avoid reactions of mismatched transfusion

• To detect weaker antigen/antibody

• To identify the blood type of an individual

Why is it important to match blood types before transfusion?

• To determine the presence of antibody

• To avoid reactions of mismatched transfusion

• To detect weaker antigen/antibody

• To identify the compatibility between donor and recipient

Negative blood types can donate to what types of blood?

• Negative only

• Positive only

• Both negative and positive

• Neither negative nor positive

What are the possible genotypes for a person with AB blood type?

• AA

• BB

• AB

• OO
