Detailed description
1. The anti Toxoplasma IgG antibody is positive (but the titer is ≤ 1 ∶ 512), and the positive IgM antibody indicates that Toxoplasma gondii continues to infect.
2. Toxoplasma gondii IgG antibody titer ≥ 1 ∶ 512 positive and/or IgM antibody ≥ 1 ∶ 32 positive indicate recent infection of Toxoplasma gondii. The rise of IgG antibody titers in double sera at acute and convalescent stages by more than 4 times also indicates that Toxoplasma gondii infection is in the near future.
3. Toxoplasma gondii IgG antibody is negative, but IgM antibody is positive. IgM antibody is still positive after RF latex adsorption test, considering the existence of window period. Two weeks later, recheck the IgG and IgM antibodies of Toxoplasma gondii. If IgG is still negative, no subsequent infection or recent infection can be determined regardless of the IgM results.
