Toxoplasma gondii Antibodies, IgG Labcorp

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.
