The Lyme Borrelia Burgdorferi IgG Antibody Test is a specialized blood test designed to detect IgG antibodies produced by the immune system in response to Borrelia burgdorferi, the bacterium that causes Lyme disease. This test is typically used when a patient has been potentially exposed to ticks and is showing signs of infection that may have persisted for weeks or even months. Unlike IgM antibodies, which appear in the early stages, IgG antibodies generally develop later, making this test particularly effective for identifying chronic or later-stage Lyme disease.The test works by analyzing a blood sample for the presence of these antibodies, which signal that the immune system has encountered the Lyme bacteria. A positive result may indicate a current or past infection, especially in patients who have compatible symptoms such as persistent joint pain, neurological issues, chronic fatigue, or cognitive difficulties. Because Lyme disease can be challenging to diagnose due to its wide-ranging and often non-specific symptoms, the IgG antibody test serves as a critical tool for confirming suspected cases.In summary, the Lyme IgG Antibody Test provides a deeper look into the body’s immune history with Lyme disease, helping healthcare providers make confident, informed choices in patient care—especially in areas where tick exposure is common or in patients with lingering unexplained symptoms.
