Toxoplasma IgG blood test

This test measures the presence of IgG antibodies specific to Toxoplasma gondii. IgG antibodies develop weeks after initial infection and typically persist for life. The test provides a qualitative result indicating whether you have been exposed to the parasite at some point. A toxoplasma IgG blood test is often combined with a test for IgM antibodies. IgM antibodies may point to a more recent infection, while IgG antibodies usually reflect past exposure.

Toxoplasmosis is usually harmless in healthy individuals but can cause serious complications in people with weakened immune systems and during pregnancy. A positive IgG result in early pregnancy may require further testing to distinguish between a past and recent infection, as a primary infection during pregnancy may pose risks to the fetus. How do people get toxoplasmosis? The parasite is often found in raw or undercooked meat. Contact with cat faeces or contaminated soil can also play a role. Cooking meat thoroughly and washing fruit and vegetables may help reduce the risk. A primary infection during pregnancy can pose risks to the baby. This is sometimes called congenital toxoplasmosis. A positive IgG test in early pregnancy may be a reason for further testing. Always discuss your results with your GP. Every blood test result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.

Testing may be recommended during pregnancy planning or early pregnancy, for immunocompromised individuals, or when toxoplasmosis symptoms are suspected. It is often ordered alongside IgM testing for a complete assessment. Consult a healthcare professional for guidance.
