Support the diagnosis of acute Toxoplasma infection. The presence of IgG antibody generally indicates past exposure and immunity. The presence of IgM antibody indicates recent infection. Elevated responses in neonates should be followed up with studies to rule out the presence of maternal antibodies, either by obtaining a convalescent specimen or by the demonstration of the absence of an IgM response.
NEGATIVE: Indicates no detectable IgM antibody to Toxoplasma. EQUIVOCAL: Presence or absence of IgM antibody to Toxoplasma cannot be determined. Another specimen should be sent for analysis. POSITIVE: Indicates detectable levels of IgM antibody to Toxoplasma. Detectable levels of Toxoplasma IgM antibody support the diagnosis of an acute primary or recurring latent infection.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
Antibody result values from different test methods and/or from different institutions cannot be compared quantitatively. Positive Toxoplasma gondii IgM results should be interpreted with caution, especially if the IgG result is negative. False positive results are possible.
