What Is the Brucella IgG Blood Test?

The Brucella IgG blood test is a diagnostic test used to measure the level of immunoglobulin G (IgG) antibodies in the blood, produced in response to an infection with Brucella bacteria. This test is valuable for diagnosing brucellosis and for monitoring the effectiveness of treatment over time.

Understanding Brucella and Brucellosis

Brucella bacteria are a group of organisms that can infect both humans and animals, causing a disease known as brucellosis. Humans typically contract the infection through direct contact with infected animals or by consuming contaminated animal products, such as unpasteurised dairy.

Common Symptoms of Brucellosis

Brucellosis often presents with flu-like or systemic symptoms, including:

Persistent fever

Fatigue

Joint and muscle pain

Night sweats

Weakness

These symptoms can become chronic if left untreated.

Role of IgG Antibodies in Brucellosis

IgG antibodies are produced by the immune system later in the course of an infection and remain in the bloodstream for a long period, often for years. The presence of IgG antibodies indicates past exposure to Brucella bacteria and a previous immune response.

When Is the Brucella IgG Test Recommended?

Individuals with signs or symptoms of long-term or chronic brucellosis

Patients undergoing treatment for brucellosis to monitor progress

People with known exposure to infected animals or animal products

High-risk professionals such as farmers, veterinarians, or abattoir workers

Interpreting Brucella IgG Test Results

Positive IgG Result: Indicates past infection or exposure to Brucella bacteria.

Negative Result: Suggests no previous exposure or immune response to the bacteria.

It’s important to note that a positive IgG result does not confirm an active infection, as antibodies may persist long after the infection has resolved.
