2 pt

This is the ability of an antigen to stimulate an antibody response.


2 pt

Immunogenicity


2 pt

This is the term for antigens that are present in less than 10% of the general population.


2 pt

Low prevalence

Low frequency

Low incidence

Familial

Private


2 pt

DAILY DOUBLE

This is a known failure of an antigen-antibody reaction to yield a positive test result as a consequence of antibody excess.


2 pt

Prozone


2 pt

This is the term for a reaction in which one cell population is agglutinated, but a second cell population remains free.


2 pt

Mixed-field


2 pt

What term has been used to denote those antibodies which react weakly both when diluted or undiluted, but are present in high concentration.


2 pt

HTLA

(High Titer, Low Avidity)


2 pt

After the ABO and Rh antigens, this antigen is the most immunogenic.


2 pt

Kell


2 pt

Name an antigen in the Kell system that is high prevalence.


2 pt

k (Cellano)

Kpb ( Rautenberg)

Jsb (Matthews)


2 pt

This antigen is formed by a non-secretor who has inherited the genes lele.


2 pt

Lec


2 pt

Anti-Tja is associated with this blood group system.


2 pt

P


2 pt

Name one antigen that is part of the C4 molecule of complement, and therefore not an intrinsic part of the RBC membrane.

(An example of an HTLA antibody)


2 pt

Chido or Rodgers


2 pt

This relatively uncommon antibody is found in up to 80% of patients with infectious mononucleosis.


2 pt

Anti-i


2 pt

This antigen, related to the Kell system, is associated with Chronic Granulomatous Disease.


2 pt

Kx


2 pt

The erythrocytes of individuals with this phenotype appear to resist invasion by

Plasmodium vivax.


2 pt

Fy (a-b-)


2 pt

The Donath-Landsteiner antibody that is present in the serum of patients with paroxysmal cold hemoglobinuria (PCH) has this specificity.


2 pt

Anti-P


2 pt

A patient with a Mycoplasma pneumoniae infection will most likely develop a cold autoantibody with this specificity.


2 pt

Anti-I


2 pt

Antibodies of the Kell system generally react at this phase of testing.


2 pt

AHG


2 pt

Give two reasons a patient who had anti-K two years ago now appears to be compatible with two random donor units of red blood cells.


2 pt

  • Both units are K negative.

  • The anti-K titer is too low to be detected.


2 pt

Name three pairs of antithetical antigens at the Kell locus.


2 pt

  • K and k (Kell and Cellano)

  • Kpa and Kpb (Penny and Rautenberg)

  • Jsa and Jsb (Sutter and Matthews)


2 pt

Individuals of the Kell null phenotype may only be transfused with RBCs from other Kell null individuals because their plasma contains this antibody.


2 pt

Anti-Ku


2 pt

A person with anti-K will be compatible with approximately this many random donors out of ten.


2 pt

9


2 pt

This enzyme is the most commonly used in routine Blood Banking.


2 pt

Ficin


2 pt

Papain is derived from this plant.


2 pt

Papaya


2 pt

Name 5 blood group antigens that are enhanced by enzymes.


2 pt

Kidd, Lewis , Rh, Ii, P, ABO

(Kidd Lewis has Ripples In his Pecs and Abs.)


2 pt

DAILY DOUBLE

Name 5 blood group antigens that are adversely affected by proteolytic substances.


2 pt

MNS, Fy, Xga

(Many New Soldiers are destroyed in the Field by eXplosions.)

Note: Sometimes Kell (Many New Soldiers are Killed in the Field by eXplosions)


2 pt

These antigens of the Duffy system are enzyme resistant.


2 pt

Fy3, Fy5 (and Fy4)
