The definition of an association constant for an antibody—antigen reaction can become more complex if the antibody—antigen reaction iavolves a multivalent antigen, as is the case when a polyclonal antisemm is used for detection of an antigen. This type of multivalent binding is termed avidity and is defined by the equation ... 

Definition of the association (or avidity) constant for such multivalent antibody—antigen reactions must consider not only the heterogeneity of the antibodies and the antigen determinant site(s), but also an apparent additive effect of binding two antigen molecules to a single antibody. Such effects lead... 

CDC Case Definition Laboratory criteria for diagnosis is (1) a positive direct fluorescent antibody test (preferably performed on central nervous system tissue) or (2) isolation of rabies virus (in cell culture or in a laboratory animal). 

CDC Case Definition A mosquito-borne viral illness characterized by acute onset and constitutional symptoms followed by a brief remission and a recurrence of fever, hepatitis, albuminuria, and symptoms and, in some instances, renal failure, shock, and generalized hemorrhages. Laboratory criteria for diagnosis is (1) fourfold or greater rise in yellow fever antibody titer in a patient who has no history of recent yellow fever vaccination and cross-reactions to other flaviviruses have been excluded or (2) demonstration of yellow fever virus, antigen, or genome in tissue, blood, or other body fluid.
