Result Interpretation

 
Unit Value
 Result
 Interpretation
< 8.0 AU/mL
 Negative
 Absence of detectable Toxoplasma gondii IgM antibodies. A negative result does not always rule out acute toxoplasmosis, because the infection may be in its very early stage and the patient has not developed Toxoplasma gondii specific IgM. If exposure to Toxoplasma gondii is suspected despite a negative finding, a second sample should be collected and tested three weeks later.
8.0 -9.9 AU/mL
 Equivocal
 The equivocal sample should be repeat tested. In case the result remains in this range after repeat testing, a second sample should be collected and tested three weeks later.
≥ 10.0 AU/mL
 Positive
 Possible presence of detectable Toxoplasma gondii IgM antibodies. A specimen with a positive result should be further tested for Toxoplasma gondii. See Table with suggested algorithm.
