Toxoplasma gondii Antibodies, IgG and IgM
Also known as: TOXO PAN
Use
The Toxoplasma gondii Antibodies, IgG and IgM test is primarily utilized for identifying visceral infection caused by Toxoplasma gondii. It is often used as a first-line test to detect the presence of IgG and IgM antibodies to determine if a current or recent infection has occurred. CDC guidelines suggest that equivocal or positive results should be retested using a different assay from another reference laboratory specializing in toxoplasmosis testing to confirm findings.
Special Instructions
Not provided.
Limitations
Low levels of IgM antibodies may persist for more than 12 months post-infection. The test is not suitable for blood donor screening or re-entry protocols. It is recommended that detected IgM results are retested in parallel with a new specimen collected 1-3 weeks later, potentially using a different test such as an IgM ELISA from a reference lab specializing in toxoplasmosis.
