Brucella - IgG antibody

Brucellosis is an infectious disease caused by the Brucella bacteria. It is typically transmitted to humans through direct contact with infected animals or by consuming unpasteurized dairy products such as milk, cheese, or butter. It is also known as “undulant fever” due to its characteristic pattern of rising and falling fever.

The Brucella - IgG antibody test detects IgG antibodies, which usually appear after the initial immune response and can persist for months or years following infection. The presence of these antibodies helps indicate past exposure to Brucella. Doctors may use this result along with symptoms, clinical history, and other tests to assess whether an infection could be active or ongoing.

Brucellosis symptoms may include undulant fever, fatigue, joint pain, muscle aches, and loss of appetite. These symptoms often resemble other illnesses such as malaria or typhoid. Laboratory testing is therefore essential to differentiate brucellosis from these conditions. This test is particularly useful for people with occupational exposure (like farmers, veterinarians, and slaughterhouse workers), those who have consumed unpasteurized dairy products, or individuals with a history of infection requiring monitoring.

No special preparation is required for this test. However, tell the doctor about all medicines/supplements and health conditions as these factors can affect the test results.

Laboratory test results may vary across laboratories. Do not self-medicate and always consult a doctor to understand the test results correctly. In some cases, repeat testing or additional confirmatory tests may be warranted.
