What is toxoplasmosis IgM?
Toxoplasmosis is an infection caused by a parasite. The test detects antibodies produced in response to an old or recent infection by the parasite. During infection, the body first produces measurable IgM antibodies in the blood 1 to 2 weeks after infection.
What is TOXO IgM positive?
A positive Toxoplasma IgM test is often considered a marker of an acute infection. However, IgM can persist for several months to years after an acute infection, thus making the distinction between an acute and a chronic infection challenging (9, 10).
What is the normal range of Toxoplasma IgM?
For AxSYM Toxo IgG and IgM tests, positive results are defined as values of ≥3 IU/ml and index values of ≥0.800, equivocal results range from 2 to 3 IU/ml and from index values of 0.600 to 0.799, and negative results are defined as <2 IU/ml and index values of <0.600, respectively.
What causes high IgM levels?
If your immunoglobulin level is high, it might be caused by: Allergies. Chronic infections. An autoimmune disorder that makes your immune system overreact, such as rheumatoid arthritis, lupus, or celiac disease.
What infections cause high IgM levels?
If your results show higher than normal levels of immunoglobulins, it may indicate:
- An autoimmune disease.
- Hepatitis.
- Cirrhosis.
- Mononucleosis.
- A chronic infection.
- A viral infection such as HIV or cytomegalovirus.
- Multiple myeloma.
- Non-Hodgkin lymphoma.
What is the relationship between IgG and IgM levels in Toxoplasma gondii?
The combination of high titers of IgG and IgM antibodies to Toxoplasma gondii is consistent with infection in the last three months. High titers of IgG and low to medium titers of IgM antibodies to Toxoplasma gondii are consistent with infection in the last three to six months.
What is the clinical significance of toxoplasmosis?
Clinical Significance. Toxoplasma Antibodies (IgG, IgM) – Toxoplasmosis is a parasitic infection caused by the protozoan Toxoplasma gondii. Approximately 23% of the immunocompetent population are asymptomatic carriers of the parasite. The combination of high titers of IgG and IgM antibodies to Toxoplasma gondii is consistent with infection in
What does IgG stand for in toxoplasmosis?
Clinical Significance Toxoplasma Antibodies (IgG, IgM) – Toxoplasmosis is a parasitic infection caused by the protozoan Toxoplasma gondii. Approximately 23% of the immunocompetent population are asymptomatic carriers of the parasite.
What is Toxo IgG avidity assay used for?
In recent decades, Toxo IgG avidity assay has been used as a standard diagnostic technique for a better estimation of the infection acquisition time and identification of the primary T. gondiiinfection during pregnancy.
