What is TOXO IgM test?
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 the difference between Toxoplasma IgG and IgM?
A positive IgG result simply means that you have been infected at some point in your life; it cannot tell you when. The IgM antibody test can tell us whether the infection was recent. A negative IgM result usually means that you’ve been infected in the past and are now immune to the parasite.
What is a IgM positive test result?
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 is the purpose of IgM?
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. For many years, IgM is thought to function by binding to antigen and activating complement system.
What are the causes of low IgG and IgM?
Low levels of the IgG antibody can also be caused by Waldenstrom’s macroglobulinemia, a rare blood cancer that is characterized by an overproduction of the IgM antibody and subsequent suppression of production of other types of antibodies, including IgG.
What does a positive herpes IgM test result mean?
A positive test result means that herpes IgM was detected in the sample. A negative result means that no IgM was detected. An equivocal test result means that the test was unable to determine whether or not there was an antibody present.
What are IgG and IgM antibodies?

What is IgA antibody?
IgA antibody is the most abundant antibody class in human serum and has a unique role in mediating immunity. IgA is a polyvalent antibody that is translocated to mucosal surfaces as the first line of defense against infections. Most of the secreted IgA lines the mucosal surfaces including respiratory,…
