Toxoplasma Gondii Antibodies Blood Test, IgG
The Toxoplasma Gondii Antibodies Blood Test is used to support the diagnosis of toxoplasmosis; document past exposure and/or immunity to Toxoplasma gondii.
The Toxoplasmosis Blood Test is used to aid in the diagnosis of infection by the parasite Toxoplasma Gondii. This test looks for IgG antibodies which typically develop as a response to infection several weeks after the initial exposure.
Toxoplasma gondii is endemic in cats and is excreted by them in their feces. Humans are easily exposed to cyst forms, and the majority develop antibody without any clinical disease. A self-limiting lymphadenitis is the most common clinical presentation in symptomatic infection. Congenital toxoplasmosis and infections in AIDS patients are more serious.
Signs and symptoms of toxoplasmosis may include:
- Swollen lymph nodes
- Fever, night sweats
- Weakness, fatigue
- Body aches
- Sometimes a sore throat
A more serious infection that affects the central nervous system, including the brain, may cause visual and mental changes or seizures, for example.
Exposure to Toxoplasma gondii comes primarily from eating undercooked or raw meat, especially pork, lamb, and venison, but can also come from unwashed fruits and vegetables that are grown in contaminated soil, from the soil itself, from contaminated water, and from unpasteurized milk.
