The present disclosure relates to a method for identifying the presence or absence of anti-Toxoplasma gondii antibodies in a human or animal serum, including placing the previously drawn serum in contact with antigens capable of binding with the anti-Toxoplasma gondii antibodies, and the observation of a bond or of an absence of a bond of antibodies with the antigens, and a combination of two recombinant GRA2 and GRA6 proteins. In particular, the antigens are attached to a support, in particular an ELISA plate. This test is preferably carried out as a supplement to another test for diagnosing toxoplasmosis.
