Exam 10: Serologic Diagnosis of Infectious Diseases

Antibodies that function by binding to and blocking surface receptors for host cells are called

The immunochemical test that involves the agglutination of an artificial carrier particle with antigen bound to its surface with antibody present in a specimen is referred to as

The antibody that primarily protects body surfaces lined with mucous membranes such as the eyes and intestines is

For accurate diagnostic of current infection, acute and convalescent sera should reflect a/an

For most pathogens, to be diagnostic of current infection, there must be

Specific proteins produced by cells of the immune system in response to the presence of foreign molecules that circulate in the serum and are present in secretions such as saliva are called

The precipitin test that is widely used for detecting antibodies against fungal infection is referred to as

Antibody-mediated immune responses produced by specific proteins are generated by

Opsonizing antibodies are

The antibody that has 10 antigen-binding sites is

Cell-mediated immune responses such as attacking and killing microorganisms or host cells damaged or infected are carried out by

Antibodies that function by attaching to the surface of pathogens and making the pathogens more amenable to ingestion by phagocytic cells are called

A method that uses an electrical current to speed up migration of an antigen and antibody is referred to as

Antibodies that function by attaching to the surface of pathogens and contributing to their destruction by the lytic action of complement are called

The presence of this antibody usually indicates recent or active infection.

The antibody that is predominantly found in tears, saliva, and intestinal secretions is

Elevations of this antibody may indicate a parasitic infection.

The difference between latex agglutination and coagglutination is

The study of the diagnosis of disease by measuring antibody levels in serum is called

Complement-fixing antibodies are
