Overview

When your body gets sick for the first time, it very quickly sets out to defend against sickness. The body produces antibodies quickly. The first antibodies produced are called Immunoglobulin M (IgM). Serum IgM test will determine the level of IgM antibody present within the blood and give the doctor an opportunity to find out if an individual has recently or currently developed an infection. The test is known as an IgM test or an IgM blood test. The Serum IgM test cost can vary from INR 300 to INR 800. The above information is designed to provide general knowledge about the test procedure, the significance of the Serum IgM test, how the test works, and what you can expect to see with your test results.

What is a Serum IgM Test?

Serum IgM Testing measures the body's response to a new infection, IgM being the first antibody created in the body following a new pathogen/virus entering the body.

IgM Antibodies provide an indication of either a current or new infection that is about to develop. In response to a new infection, IgM antibodies are produced by the body as an immediate response to that new pathogen (virus).

Serum IgM testing is especially important in pregnant women because some of the infections detectable by IgM testing can cause miscarriage or developmental abnormality if left undetected.
