WebToxoplasmosis can be diagnosed by various methods, including antibody detection using serological tests, and parasite DNA determination by polymerase chain reaction (PCR). The most widely utilized technique nowadays is antibody detection, which provides serological proof of immunoglobulin (Ig)G and IgM antibodies specific to T. gondii antigens. WebIgM. IgM (“Immunoglobulin M”) is the second or third most abundant antibody in circulation (after IgG and often, IgA). This antibody is composed of five individual antibody “monomers” bound together by disulfide bonds. Since each individual antibody has two binding sites, each IgM has a total of 10 places to bind antigen.
