Toxoplasma Antibodies (IgG, IgM)
- Ordering Info
The U.S. Food and Drug Administration (FDA) is advising physicians that they should not use the result from any one Toxoplasma IgM commercial test kit as the sole determinant of recent Toxoplasma infection when screening a pregnant patient. Because these tests can have false-positive results, reliance on a single test result could lead to misdiagnosis, resulting in unnecessary treatment of the patient and/or termination of the pregnancy.
See laboratory report
Toxoplasmosis is a parasitic infection caused by the protozoan Toxoplasma gondii. Approximately 23% of the immunocompetent population are asymptomatic carriers of the parasite. The combination of high titers of IgG and IgM antibodies to Toxoplasma gondii is consistent with infection in the last three months. High titers of IgG and low to medium titers of IgM antibodies to Toxoplasma gondii are consistent with infection in the last three to six months.
