Toxoplasmosis, IgG

Toxoplasmosis is an infection that is caused by a parasite that is common amongst the general population. This test measures the presence of IgG antibodies against the parasite in the blood.

Toxoplasmosis is an infection that is caused by a parasite that is common amongst the general population. Because it has a low virulence, it rarely produces symptoms since the body clears the parasite quickly. In people who are immunocompromised, such as those with HIV or organ transplant receivers, the infection can be severe. This test measures the presence of IgG antibodies against the parasite in the blood. IgG antibodies against toxoplasmosis start to rise after several weeks of initial infection. At a point when the infection has been resolved, the level of IgG antibodies plateaus, providing the host with lifelong immunity to toxoplasmosis. IgG, along with IgM are useful in determining whether there is active toxoplasmosis disease or if there was previous exposure to the parasite.

This test is performed in following conditions such as:

• Swollen lymph nodes
• Fever, night sweats
• Weakness, fatigue
• Headache
• Body aches
• Sometimes a sore throat
