EE SERO Flashcards
A major advantage of passive immunization compared to active immunization is that
Antibody is available more quickly
The strength with which a multivalent antibody binds a multivalent antigen is termed the
B. Avidity
How does the secondary humoral immune response differ from the primary response?
The antibody levels produced are higher in the secondary immune response.
After activation of the complement system, leukocytes and macrophages are attracted to the site of complement activation by
C5a
The type of immunity that follows the injection of an immunogen is termed
Artificial active
The type of immunity that follows the injection of antibodies synthesized by another individual or animal is termed
Artificial passive
Innate immunity includes
Phagocytosis by polymorphonuclear cells
The agglutination pattern shown in Color Plate 23• was observed while performing an antibody titration. This agglutination pattern is an example of
A prozone reaction
The antibody most frequently present in systemic lupus erythematosus is directed against
Nuclear antigen
The rapid plasma reagin assay for syphilis does not need to be read microscopically because the antigen is
Complexed with charcoal
The Venereal Disease Research Laboratory (VDRL) test for syphilis is classified as a(n)
Flocculation reaction
One cause of a false-positive VDRL test is
Systemic lupus erythematosus
The portion of an antigen that binds to an antibody or T cell receptor is called a(n)
Epitope
Identical antibodies produced from a single clone of plasma cells describes
Monoclonal antibodies
IgM antibodies react well in complement fixation (CF) tests. Because of this, CF tests for antibodies should
Be positive early in the course of the disease
Which of the following serologic tests is commonly performed by an immunofluorescence method?
Antinuclear antibody (ANA)
The Fab portion of an antibody
Contains the hypervariable reagion
