Answer

The Sabin-Feldman dye test is a sensitive and specific neutralization test for toxoplasmosis. It is used to measure primarily IgG antibody and is the standard reference test for toxoplasmosis. However, it requires live T gondii organisms; therefore, it is not available in most laboratories. (It is used primarily as a confirmatory test in reference laboratories.) High titers suggest acute toxoplasmosis. [49]
