Difference between IgG and IgM

A major difference between the two antibodies is related to exposure. Although IgM antibodies are usually found in a human body after being exposed to a disease, IgG is the body's long-term response to a disease. For example, if a child is exposed to chicken pox, he will show increased blood IgM results in the post-exposure period. Once the child develops the disease, it acquires long-term immunity by developing IgG antibodies. While IgM is an indicator of a current infection, an IgG indicates a recent or previous exposure to the disease.

IgM is the first antibody the body produces in an acute infection. It is about six times larger than IgG and is multivalent. This means it has multiple binding sites. In the case of IgM, the number of binding sites is 10! However, only about half of this can actually bind to an antigen.

IgM is a temporary antibody that disappears in two or three weeks. It is then replaced by IgG that will last a lifetime and provide the person with lasting immunity.

Summary: 1. IgM is the direct antibody that is produced when a human body is exposed to a bacteria, virus, or a toxin 2. IgG is found throughout the body, mainly in most body fluids, while IgM is found mainly in the blood and lymphatic fluids. 3. IgM is greater than IgG 4. IgM is temporary and disappears after a few weeks. It is then replaced by IgG.

What does IgM and IgG mean

There are two types of antibodies to test for: IgM and IgG.

IgM is first produced by the body and then IgG.

After a bite, it takes a few weeks before enough antibodies are produced to show.

IgM usually disappears after a few months,

It is also possible that a lost IgM becomes positive over time. IgM, according to some experts, is indicative of a persistent active infection.

IgM is only produced if there was recent contact with the antigen (the bacteria), because the cells that produce IgM do not have an “immunological memory”.

IgG, on the other hand, can remain detectable in the body for years, even after the bacteria has disappeared from the body. A positive test for IgG can therefore be appropriate for a longer-lasting active infection as well as for a cured infection. When there is a negative result, it is called seronegativity. Seronegativity has been shown to occur with an active infection.

Test results alone cannot be used to establish or rule out the diagnosis with certainty. In many cases, only a combination of data can lead to the (most likely) diagnosis. A nuanced form of diagnostics in which clinical data also play an important role and in which the different degrees of certainty are expressed is recommended.
