Description:
The Lyme Disease Immunoblot IgG test is typically used as a confirmatory test for people who have had positive results from previous Lyme Disease testing. This test looks for the presence of IgG antigen bands which can confirm a previous exposure. The detection of multiple bands is required for a positive result. The CDC does not recommend the Immunoblot test as a front line screening as some conditions other than Lyme Disease may cause a false positive. Typically, antibody testing such as the Lyme Total Antibodies Test is done as a first screening.
Lyme Disease is caused by infection with the bacteria Borrelia burgdorferi. It is most commonly spread by the Deer Tick or Black-Legged Tick and is the most common tick-borne illness in the United States and Europe. Lyme disease can be difficult to diagnose because the symptoms are often similar to other afflictions. While some people will display a distinctive "bulls-eye" rash around the site of the bite, others may experience common flu-like symptoms such as fever, chills, fatigue, and headache. The ticks which spread the disease are typically very small (the size of a pinhead) and many people do not even realize they have been bitten. If left untreated, Lyme Disease can cause joint pain, numbness in the arms and legs, facial paralysis, Meningitis, heart problems, or memory problems.
This test is typically ordered after a person has had a positive result from a Lyme screening test. This Immunoblot test only looks for past exposure. For a test which looks for both recent and past exposure, please see our Lyme Disease Immunoblot IgM & IgG test.
Turnaround time for the Lyme Disease Immunoblot test is typically 2-5 business days.
