Indirect detection is performed in pregnant women and in immunocompromised patients. Detection of immunoglobulin G (IgG) is possible within 2 weeks of infection using the enzyme-linked immunosorbent assay (ELISA) test, the IgG avidity test, and the agglutination and differential agglutination tests. (Acute and convalescent sera have no role in the indirect detection of toxoplasmosis.)
