ABO System
This is the characteristic color used to identify anti-B.
What is yellow
This modified red blood cell product is prepared by removing most plasma proteins, reducing the risk of allergic transfusion reactions and preventing complications in IgA-deficient patients.
What are washed RBCs
This transfusion reaction is characterized by hives and itching
What is urticarial / allergic reaction
A screening test used to detect Fetal-Maternal Hemorrhage. Able to detect a bleed of 10mL or more
What is the Rosette Test
This null phenotype, marked by the absence of both common antigens in its system, is associated with resistance to Plasmodium vivax infection.
What is Duffy null
Fy(a-b-)
Offspring can potentially express all four common blood types when parents with these two phenotypes are paired.
What is A and B
This blood product is created by combining packed red blood cells with plasma to approximate whole blood, often used in exchange transfusions or neonatal transfusion scenarios.
What are reconstituted RBCs
Anaphylactic transfusion reactions may occur in patients with a deficiency of this immunoglobulin.
What is IgA
This condition is caused by maternal antibodies against antigens on fetal red cells inherited from the father
What is Hemolytic Disease of the Fetus and Newborn (HDFN)
This extremely rare null phenotype, defined by the absence of the H antigen and associated with a naturally occurring hemolytic anti-H, requires individuals to receive transfusions only from others with the same phenotype
What is the Bombay phenotype
These red blood cells show the strongest agglutination when tested with Ulex europaeus lectin
What are group O red blood cells?
This blood product, rich in fibrinogen, factor VIII, von Willebrand factor, and factor XIII, is commonly used to treat hypofibrinogenemia.
What is Cryoprecipitate
A quick way to assess for a possible acute hemolytic transfusion reaction is to spin down a post-reaction specimen and look for this
What is hemolysis
One dose of Rh immune globulin will protect the mother from a whole blood bleed up to this amount
What is 30mL
This null phenotype produces red blood cells resistant to lysis in 2M urea, and is found in Polynesian populations.
What is Jk null
Jk(a-b-)
This approximate percentage represents how many individuals with group A can be further classified as subgroup A1.
What is 80% of group A individuals
Red blood cells preserved for long-term frozen storage must be kept under this ultra-low temperature condition, typically at or below this value.
What is ≤ -65°C
Clinical signs of this reaction include chills, shock, flank pain, renal failure and DIC. This type of reaction is often due to clerical error.
What is an Acute Hemolytic Transfusion Reaction
Toxic levels of unconjugated bilirubin in an infant's brain is called
What is Kernicterus
This null phenotype occurs in a blood group system whose antigens are expressed in body fluids like saliva and are closely associated with an individual’s secretor status.
What is Lewis null
Le(a-b-)
The presence of blood group A is confirmed by detecting this specific immunodominant sugar molecule on the red cell surface
N-acetyl-D-galactosamine
Apheresis platelets must maintain a pH of at least this value at the end of their storage period to remain acceptable for transfusion
What is 6.2
This serious transfusion reaction is characterized by acute lung injury, hypoxemia, and non-cardiogenic pulmonary edema occurring within six hours of transfusion
What is TRALI
This elution method uses freezing and thawing to disrupt antigen-antibody interactions on red blood cells, commonly used to recover bound antibodies such as in cases of hemolytic disease of the newborn
What is Lui Freeze-Thaw Elution
This null phenotype results in red blood cells lacking Glycophorin A and Glycophorin B, eliminating all antigens carried on those structures and effectively removing an entire blood group system.
What is the MkMk phenotype
