Special Info
Grossly hemolyzed or lipemic samples as well as samples containing particulate matter or exhibiting obvious microbial contamination will be rejected. Bacterial contamination or heat inactivation of the specimen may affect the test result. The concentrations of anti-Toxoplasma gondii IgG in a given specimen determined with assays from different manufacturers can vary due to differences in assay methods and reagent specificity.
Clinical Info
The magnitude of the measured result is not indicative of the amount of antibody present. Equivocal results should have a new sample collected and tested no less than one or two weeks later.
Clinical Limitation
Do not rely on any single test result as the sole determinant in diagnosing recently acquired infection. If acute infection is suspected, a patient sample should be tested for the presence of Toxoplasma – specific IgG and IgM Antibodies.
