Clinical Significance
T. gondii IgM is typically detected within a few days of infection, peaks within a few weeks, and usually falls to undetectable levels within a few months. In some patients, however, T. gondii IgM persists for more than a year; Thus, detection of T. gondii IgM does not necessarily indicate recent or ongoing toxoplasmosis.
