IgM Antibodies

IgM (Immunoglobulin M) is a type of antibody that is produced by the body as a first response to infections, making it a crucial component of the immune system's initial defense mechanism. In the context of testing, IgM antibodies are often measured to diagnose recent infections, including Lyme disease caused by the Borrelia burgdorferi bacterium. The presence of IgM antibodies against specific pathogens in the blood can indicate a recent exposure to or infection by that pathogen. Due to their rapid response and short lifespan in the circulation, IgM levels can provide valuable information about early stages of infections....

What is the significance of IgM testing in Lyme disease?

IgM testing is important in the diagnosis of Lyme disease as it helps detect early infection. IgM antibodies to Borrelia burgdorferi typically appear within a few weeks of infection, making this test useful for identifying recent exposure to the tick-borne bacterium.

Who should undergo IgM testing for Lyme disease?

Individuals who have been bitten by a tick or have been in areas where Lyme disease is common and present with symptoms such as fever, rash (erythema migrans), fatigue, and joint pain should undergo IgM testing. Early detection is crucial for effective treatment.
