Support the diagnosis of Toxoplasma infection. The presence of IgG antibody generally indicates past exposure and immunity. The presence of IgM antibody indicates recent infection. Single IgG levels are not useful for supporting the diagnosis of an acute infection. Elevated levels in neonates should be followed up with studies to rule out the presence of maternal antibodies by demonstrating the absence of an IgM response.
NEGATIVE: No detectable IgG antibody to Toxoplasma. EQUIVOCAL: Presence or absense of IgG antibody to Toxoplasma cannot be determined. Another specimen should be sent for analysis. POSITIVE: Detectable levels of IgG antibody Toxoplasma. Detectable levels of Toxoplasma antibody indicate exposure to Toxoplasma gondii.
The performance characteristics of this test have not been established for CSF, neonates, infants or cord blood. This is a qualitative test; quantitation for comparison of acute and convalescent sera has not been validated by the manufacturer of the current test system. Result values from different methodologies or from different institutions cannot be compared.
