The Toxoplasma antibody test checks for exposure to Toxoplasma gondii, a common parasite found in cat feces and undercooked meat. This test is a critical part of the TORCH Panel. It measures both IgG (past exposure) and IgM (active infection) antibodies. An active infection during pregnancy can be very serious for the baby. This test is essential for all women planning a family. A simple blood draw provides this vital information, helping you understand your risk and take simple, protective precautions.
