Diagnosing a recently acquired, primary Toxoplasma infection is not easy, in that the IgM antibodies (a typical marker for recent infections) developed during toxoplasmosis may persist for many months and even for years. Measuring the avidity of specific IgG was demonstrated to be particularly useful for this purpose. As a matter of fact, the initial IgG antibody response to infection is characterized by antibodies with low avidity, in which binding to the specific antigen sites is easily dissociated.

ToxoplasmaEIA-IgG-Avidity kit is designed for detection of IgG antibodies avidity for Toxoplasma gondii in human serum or plasma by enzyme immunoassay method – ELISA (Sandwich assay).
