Bartonella IgM

What Is Bartonella IgM?

Bartonella IgM refers to the presence of immunoglobulin M (IgM) antibodies in the blood that are produced by the immune system in response to an acute infection with Bartonella bacteria. IgM antibodies are typically the first line of immune defence and are produced during the early stages of infection.

Understanding Bartonella Infections

Bartonella is a genus of bacteria responsible for several infectious diseases in humans, including:

Cat scratch disease

Trench fever

Bartonellosis

These infections can vary in severity and may present with symptoms such as fever, swollen lymph nodes, fatigue, and muscle pain. Transmission often occurs through scratches or bites from infected animals (particularly cats), or through contact with body lice or fleas.

Role of the Bartonella IgM Blood Test

The Bartonella IgM blood test is used to detect an active or recent infection by identifying IgM antibodies in the bloodstream. A positive result indicates that the individual's immune system is actively responding to a current Bartonella infection.

When Bartonella IgM Testing Is Recommended

Unexplained fever or lymph node swelling

Recent exposure to cats, fleas, or lice

Symptoms suggestive of cat scratch disease or trench fever

Assessment of acute infectious symptoms in immunocompromised patients
