Which of the following best describes what is occurring in the slide latex agglutination test for rheumatoid factor when the test is positive?
a. Patient produced rheumatoid factor binds to the IgG bound to the carrier particles producing agglutination.
b. Reagent IgG binds to the patient's red cells if they have produced rheumatoid factor inhibiting agglutination.
c. Patient produced rheumatoid factor binds to reagent antigens bound to the slide and then latex particles adhere and show color if RF is present.
d. Murine IgM binds to the patient IgG that has bound to the latex particles in the test, producing agglutination.
