Useful For
Qualitative detection of IgM antibodies to Toxoplasma gondii in serum
Highlights
Detection of IgM-class antibodies to Toxoplasma gondii may be useful as a screen for recent infection with T gondii. Per the US Food and Drug Administration, IgM-positive results by a screening assay should be confirmed by a Toxoplasma reference laboratory. A single negative result by this assay does not rule-out toxoplasmosis as the specimen may have been collected too early following infection, prior to development of detectable antibodies.
