LIMITATIONS OF TEST: Negative results do NOT preclude recent primary T. gondii infection. If known exposure to T. gondii, the diagnosis should NOT be based solely on this test result, but should be confirmed by another method.
ADDITIONAL INFORMATION: The presence of IgM antibodies to T. gondii indicates a primary, reactivation, or reinfection with T. gondii. It does not differentiate active from resolving or resolved infection.  To differentiate these stages of infection, additional testing, including IgG avidity testing, antigen detection, or PCR needs to be done.  Contact a Microbiology laboratory director or supervisor for guidance. Click here for more information on Toxoplasmosis
