Acute Toxoplasmosis (IgM) Diagnosis - Toxoplasma IgM Antibody Test

A serological test detects the presence and titer of immunoglobulin M (IgM) antibodies against the Toxoplasma gondii parasite. These antibodies appear within one to two weeks of the initial acute infection, peak, and then begin to decline over several months (usually 6–9 months). Their presence is a strong indicator of a recent or active infection and is crucial in assessing the risk of fetal transmission during pregnancy.
