HelpTest ID TXM Toxoplasma gondii Antibody, IgM, Serum
Useful For
Detecting recent infection with Toxoplasma gondii
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, for example, 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.
