Toxoplasma gondii Antibodies, IgG
Also known as: Toxoplasmosis
Use
Qualitative determination of IgG antibodies to Toxoplasma gondii (T. gondii) to aid in the determination of immune status of individuals including pregnant women. If IgG antibody is detected, it is recommended that IgM testing be performed if more precise knowledge of the time of infection is needed (e.g., pregnant women). A positive IgM but a negative IgG result should be viewed with suspicion; the patient should be retested two weeks after the first test. If the patient is pregnant and IgG/IgM positive, an IgG avidity test should be performed.

Interpretation of results should consider possible cross-reactivity and the clinical context in which results are obtained. False-positive results can occur, especially in the presence of rheumatoid factor or other interfering substances.
