The immunoblot test is also known as a Lyme Disease Line Blot test. The Lyme Disease Immunoblot test is typically used as a confirmatory test for people who have had positive results from previous Lyme Disease testing.

A Western Blot test should be ordered as a follow-up to a positive result on an antibody test. An initial screening is usually done with an antibody test. Testing should also be considered by anyone who has been in an area where Deer Ticks are known to be common. Testing for Lyme Disease is advised when a person is experiencing symptoms associated with Lyme, especially if they have had a recent tick bite or have been in an area where Lyme Disease is prevalent. If left untreated, Lyme Disease can cause joint pain, numbness in the arms and legs, facial paralysis, Meningitis, heart problems, or memory problems. 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. 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.
Lyme disease can be difficult to diagnose because the symptoms are often similar to other afflictions. 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 is caused by infection with the bacteria Borrelia burgdorferi. The CDC does not recommend the Western Blot test as a front-line screening as some conditions other than Lyme Disease may cause a false positive. The detection of multiple bands is required for a positive result. This test looks for the presence of both IgG and IgM antigen bands to confirm both recent and previous exposure. The immunoblot test is also known as a Lyme Disease Line Blot test.

Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations. Since it can take several weeks or months before antibodies are found in blood, the Western blot test may not always be reliable. If it causes a change in color, antibodies to a specific infection have been detected.
The proteins are placed onto blotting paper that’s made from a material such as nitrocellulose.Īn enzyme is added to the paper. The Western blot uses a procedure called gel electrophoresis to identify and separate proteins by molecular weight and length. Antigens stimulate your immune system to push out antibodies in an effort to fight the disease. If you develop a viral, fungal, or bacterial infection, your body will produce proteins called antigens in response. The Western blot test looks for the antibodies against an infection, not the infection itself. If you get a positive result for Lyme disease or HIV after taking an enzyme-linked immunosorbent assay (ELISA) test, your doctor may recommend a Western blot test to you. It was invented in 1979 to identify ribosomal RNA binding proteins. The Western blot test is also known as a protein immunoblot test or immunoblotting.
