ABO Basics
This blood group is known as the universal donor for red cells
What is O negative
The most immunogenic red cell antigen after ABO
What is D antigen
The test used to detect unexpected antibodies in patient plasma
What is an antibody screen
Most common transfusion reaction
What is a febrile non-hemolytic transfusion reaction
Packed red blood cells are typically stored at this temperature range
What is 1–6°C
This antigen is formed by the addition of N-acetylgalactosamine to the H antigen
What is A antigen
A patient who lacks the D antigen is considered this Rh type
What is Rh negative
Antibodies reacting best at 37°C are considered this type
What are warm antibodies
This reaction is caused by recipient antibodies against donor plasma proteins
What is an allergic transfusion reaction
This component is used to treat thrombocytopenia
What are platelets
Patients with this ABO type have both anti-A and anti-B antibodies
What is group O
This Rh antibody can cause severe HDFN
What is anti-D
This antibody shows dosage and is commonly missed in heterozygous cells
What is anti-Jka (or Kidd antibodies)
Clerical errors are the most common cause of this serious reaction
What is an acute hemolytic transfusion reaction
Platelets are stored at this temperature with continuous agitation
What is 20–24°C
Lack of the H antigen results in this rare blood phenotype
What is Bombay (Oh) phenotype
Kell system antibodies are clinically significant and usually of this Ig class
What is IgG
Panel cells lacking a specific antigen help accomplish this step
What is rule-out
This reaction presents with hypoxia and pulmonary edema without circulatory overload
What is TRALI
This plasma product contains all clotting factors
What is Fresh Frozen Plasma (FFP)
ABO antibodies are primarily this immunoglobulin class
What is IgM
This antigen system includes Fya and Fyb
What is the Duffy blood group system
Autoantibodies commonly cause this test to be positive
What is the DAT (Direct Antiglobulin Test)
Immediate first action when a transfusion reaction is suspected
What is stop the transfusion
The shelf life of thawed plasma (1–6°C)
What is 5 days
