The Toxoplasmosis Blood Test is used to aid in the diagnosis of infection by the parasite

Toxoplasma Gondii. This test looks for IgG antibodies which typically develop as a response

to infection several weeks after the initial exposure.A positive IgG result simply means

that you have been infected at some point in your life; it cannot tell you when. The IgM

antibody test can tell us whether the infection was recent. A negative IgM result usually

means that you've been infected in the past and are now immune to the parasite
