When someone is exposed to Toxoplasma gondii (T. gondii), their immune system responds by producing antibodies; 2 types of Toxoplasma antibodies may exist in the blood: IgM and IgG.
1. IgM antibodies are the 1st to appear in response to a Toxoplasma infection. They are present in most individuals within a week or two after the initial exposure. IgM antibody production rises for a short time period and declines. Eventually, sometimes months after the initial infection, the level (titer) of Toxoplasma IgM antibody falls below detectable levels in most people. Additional IgM may also be produced when dormant T. gondii is reactivated and/or when a person has a chronic infection.
2. IgG antibodies are produced several weeks after the initial infection to provide long-term protection. Levels of IgG rise during the active infection, then stabilize as the Toxoplasma infection resolves and the parasite becomes inactive. Once a person has been exposed to T. gondii, they will have some measurable amount of IgG antibody in their blood for the rest of their life. T. gondii IgG antibody testing can be used, along with IgM testing, to help confirm the presence of a recent or previous Toxoplasma infection.
if the results show a recent infection by toxoplasmosis then you have to wait for 6 month before conceiving (getting pregnant)
