Toxoplasma IgM Antibody Test

The Toxoplasma IgM Antibody Test measures IgM antibodies against Toxoplasma gondii, a parasite that can cause toxoplasmosis. The presence of IgM antibodies may indicate a recent or active infection, although positive results may require confirmatory testing because IgM antibodies can persist for months after infection. This test is commonly used to evaluate suspected acute toxoplasmosis, particularly during pregnancy or in individuals with weakened immune systems. Results help support diagnosis, guide additional testing, and inform appropriate clinical management when recent infection is a concern.
