Toxoplasma gondii – IgM Antibodies

Toxoplasma gondii is a parasitic organism that can infect humans through contaminated food, water, undercooked meat, or contact with cat feces. The IgM antibody test is used to identify recent or active infection, as IgM antibodies appear early after exposure.

This test is especially important during pregnancy, as acute toxoplasmosis can be transmitted from mother to fetus and may cause serious complications such as congenital infections, neurological damage, or miscarriage. It is also useful in immunocompromised individuals, including patients with HIV/AIDS or those on immunosuppressive therapy. The IgM test is often interpreted along with Toxoplasma IgG and avidity testing for accurate diagnosis and infection timing.
