Occasionally, people may have a few weeks or months of mild, flu-like illness such as muscle aches and tender lymph nodes. Toxoplasmosis is an infection caused by the parasite Toxoplasma can be made by serologic testing or by molecular testing. A toxoplasma, or toxoplasmosis, test is a blood test that determines if you have the antibodies to protect your body from the Toxoplasma gondii parasite in your body.
Gondii-specific antibodies usually appear within 1 to 2 weeks of the infection, peak within 1 to 2 months, fall at variable rates. After observing a patient with systemic lupus erythematosus (SLE) who had a positive toxoplasma IFA test but a negative dye test, we studied sera with high titers of antinuclear antibodies from 16 SLE patients and from 2 with rheumatoid arthritis for Toxoplasma antibodies in the immunoglobulin G and M (IgG and IgM) IFA tests and the dye test. She has the IgG type of antibody, which will indicate an infection occurred in the past and the baby does not have a chance of getting infected.

Although tests for detection of immunoglobulin M (IgM) toxoplasma antibodies have been reported to have a high degree of accuracy, it is well recognized by investigators in the United States and. A few months later, IgM becomes undetectable and is replaced by IgG antibodies that will be present for the rest of the person's life.
Lockdowns and hygienic measures around the world are based on numbers of cases and mortality rates created by the so-called SARS-CoV-2 RT-PCR tests used to identify "positive" patients, whereby "positive" is usually equated with "infected. The clinical detection sensitivity and specificity of this test were measured using blood samples collected from 397 PCR confirmed COVID-19 patients and 128 negative patients at eight different clinical sites. The DT is a sensitive and specific neutralization test in which live organisms are lysed in the presence of complement and the patient's IgG T.
