Exam 9: Immunochemical Methods Used for Organism Detection

A positive latex agglutination test was observed in a sample containing Cryptococcus neoformans.The specimen of choice to identify this pathogen is:

The difference between latex agglutination and coagglutination is:

Monoclonal antibodies are those that:

The major advantage of immunofluorescent microscopy assays is that:

A sample suspected of containing Legionella pneumophila is treated with the dye fluorescein isothiocyanate (FITC); however, the sample fluoresced a bright apple-green colony after it was processed.Which of the following statements explains this discrepancy?

Polyclonal antibodies are those that:

A modification of the Ouchterlony method that speeds up the migration of an antigen and antibody by applying an electrical current is referred to as:

The precipitin test that involves antigen and antibody diffusing toward each other, producing a visible precipitin band at the point at which they meet, is referred to as:

A test procedure that applies a specific fluorescent dye-antibody complex to a slide to which the patient specimen has been applied is referred to as a(n):

The immunochemical test that involves an antigen present in a specimen binding to the combining sites of the antibody exposed on the surfaces of latex beads is referred to as:
