Toxoplasmosis Test

Why It Is Done

A toxoplasmosis test is done to check if a:

• Pregnant woman has antibodies from a toxoplasmosis infection. If the IgG type of antibody is present, it means an infection occurred in the past and the baby does not have a chance of becoming infected. If the IgM type of antibody is present, it means the infection is recent and the baby does have a chance of becoming infected.
• Baby has toxoplasmosis.
• Person with a weakened immune system, such as someone who has HIV, has a chance of getting a toxoplasmosis infection.
