Exam 10: Precipitation and Particle Agglutination Methods

Match the type of immunoglobulin with the optimal thermal range. -IgG

Match the term with the appropriate description. -Prozone phenomenon

In nephelometry measurement, if antigen overwhelms the quantity of antibody, the measured signal

In nephelometric methods, the relationship between the protein being assayed (the antigen in this instance) and the concentration of the protein in the sample (as measured by the instrument as the amount of scattered light) is

Match the cause of a false-positive agglutination reaction with the appropriate corrective measure. -Over centrifugation of cells and serum

Match the following terms with the correct definition. -Hemagglutination

All the following procedures are typically performed by latex agglutination or latex agglutination inhibition assays except

A false-positive latex agglutination assay for pregnancy can be produced by all the following except:

Match the cause of a false-negative agglutination reaction with the appropriate corrective measure. -Postzone phenomenon

With agglutination inhibition in pregnancy testing, a negative result is evidenced by

Cryoglobulins are proteins that precipitate or gel when cooled to

The lattice hypothesis states that an optimal reaction occurs between antigen and antibody when

Match the cause of a false-negative agglutination reaction with the appropriate corrective measure. -Anti-human globulin (AHG) malfunction

If a slide agglutination test is rotated for less than 1 minute, as the directions specify, what source of error can occur?

Match the cause of a false-positive agglutination reaction with the appropriate corrective measure. -Autoagglutination
