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
This test should not be used for blood donor screening, associated re-entry protocols, or for screening human cell, tissues, and cellular- and tissue-based products (HCT/P). It is recommended for clinical diagnostic use in identifying toxoplasmosis infections.
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.
