The test for Toxoplasma gondii requires checking for Toxoplasma gondii antibodies. The most common method used for Toxoplasma gondii testing is to detect Toxoplasma gondii antibodies in the serum, which are the specific antibodies IgG and IgM, and these two antibodies are not affected by eating. Toxoplasma gondii infection is most common as a latent infection. When women undergo a preconception checkup, they are not usually tested for Toxoplasma gondii only, but for the eugenics five tests, which include rubella virus, herpes, herpesvirus, toxoplasma gondii test, and cytomegalovirus test. A positive IgG test for Toxoplasma gondii in the eugenics test represents a previous infection and generally does not require treatment. If there is a positive IgM, it indicates ongoing infection, and treatment will need to be given according to the indicator.
