What is immunoglobulin IgM test?
An immunoglobulin (im-yeh-no-GLOB-yeh-len) test measures the level of types of antibodies in the blood. The immune system makes antibodies to protect the body from bacteria, viruses, and allergens.
What does a positive IgM indicate?
IgM is usually the first antibody produced by the immune system when a virus attacks. A positive IgM test indicates that you may have been infected or that you have recently been vaccinated and your immune system has started responding to the vaccination and that your immune system has started responding to the virus.
What does it mean if your IgM is high?
High levels of IgM can mean macroglobulinemia, early viral hepatitis, mononucleosis, rheumatoid arthritis, kidney damage (nephrotic syndrome), or a parasite infection is present.
What is the function of immunoglobulin IgM?
Immunoglobulin (Ig) M is the first antibody isotype to appear during evolution, ontogeny and immune responses. IgM not only serves as the first line of host defense against infections but also plays an important role in immune regulation and immunological tolerance.
What does Covid IgG positive mean?
The presence of IgG suggests that the infection happened weeks to months in the past. It also suggests that you may no longer be infectious. IgG indicates that you may have some immunity to the virus, though you may not. How much it might protect you from getting sick with COVID-19 in the future is unknown.

- weakness.
- fatigue.
- loss of appetite.
- fever.
- sweats.
- weight loss.

Why IgM is considered as best agglutinin?
IgM can recognize epitopes on invading microorganisms, leading to cell agglutination. This antibody-antigen immune complex is then destroyed by complement fixation or receptor-mediated endocytosis by macrophages.
How do you fix high IgM?
Hyper IgM syndrome types 2, 4, and 5 can often be treated with immunoglobulin replacement therapy alone. However, sometimes prophylactic antibiotic therapy will be recommended for individuals who develop chronic complications such as bronchiectasis or recurrent sinus infections.
