Borrelia IgG Antibodies
Borrelia IgG antibodies are antibodies produced by the immune system in response to exposure to Borrelia bacteria, which are associated with Lyme disease or borreliosis. IgG antibodies usually develop later than IgM antibodies and may remain detectable for an extended period. In this test, IgG can support interpretation of previous exposure or a later immune response, but results should be assessed together with symptoms, tick exposure history and other relevant clinical information.
Description
What is the significance of IgG testing in Lyme disease?
IgG testing is crucial for detecting later stages or past exposure to Lyme disease. IgG antibodies to Borrelia burgdorferi typically develop several weeks to months after initial infection and can persist for years, making this test useful for identifying chronic or previous infections.
Who should undergo IgG testing for Lyme disease?
Individuals with long-term symptoms that suggest Lyme disease, such as chronic joint pain, neurological symptoms, and fatigue, should consider IgG testing. It is also recommended for those who have had a previous positive Lyme disease test or who have been treated for Lyme disease in the past.
How is IgG testing performed for Lyme disease?
The test involves analyzing a blood sample for the presence and concentration of IgG antibodies specific to Borrelia burgdorferi. Higher levels of these antibodies suggest a later stage or a past infection.
How does IgG testing differ from IgM testing in Lyme disease?
IgG and IgM antibodies serve different roles in the immune response to Lyme disease. IgM antibodies appear first, within a few weeks of infection, indicating recent exposure. IgG antibodies develop later, remain longer, and indicate past exposure or ongoing infection. Testing for both types of antibodies at different stages can provide a more complete picture of the infection timeline.
Tests containing this item
GetTested’s Lyme Disease Test (IgG/IgM) is a rapid test designed for the qualitative detection of antibodies against Borrelia burgdorferi in blood samples. The test detects both IgM and IgG antibodies, providing an indication of either a current or past exposure to the bacteria. Results are available within approximately 10 minutes.
