Lyme Disease Antibodies (IgG), Immunoblot details
What Lyme Disease Antibodies (IgG), Immunoblot shows
The Lyme IgG immunoblot separates proteins from Borrelia burgdorferi, the bacterium that causes Lyme disease, and checks which of them your IgG antibodies react with, each reaction showing as a band. This result is the overall interpretation, reported as positive or negative based on how many of a set of specific bands are present, following CDC criteria. It is used as the second step after a positive or equivocal Lyme screening test. A positive result supports past or current infection, since IgG can remain for a long time after treatment. Single bands are never interpreted alone, and results are read alongside your symptoms and likely tick exposure.
Tests that include Lyme Disease Antibodies (IgG), Immunoblot
This test checks for Lyme disease, which is spread by ticks carrying Borrelia burgdorferi. It uses a method called Immunoblot to look for specific antibodies in your blood with high accuracy. This is usually done to confirm results from other tests like EIA or IFA.
- 18 KD (IgG) Band Shows whether your IgG antibodies react to the 18 kD protein of the Lyme bacterium, one band read as part of a Lyme disease immunoblot pattern.
- 23 KD (IgG) Band Shows whether your IgG antibodies react to the 23 kD protein of the Lyme bacterium, one band read as part of a Lyme disease immunoblot pattern.
- 23 KD (IgM) Band Shows whether your IgM antibodies react to the 23 kD protein of the Lyme bacterium, one band read as part of a Lyme disease immunoblot pattern.
- 28 KD (IgG) Band Shows whether your IgG antibodies react to the 28 kD protein of the Lyme bacterium, one band read as part of a Lyme disease immunoblot pattern.
- 30 KD (IgG) Band Shows whether your IgG antibodies react to the 30 kD protein of the Lyme bacterium, one band read as part of a Lyme disease immunoblot pattern.
- 39 KD (IgG) Band Shows whether your IgG antibodies react to the 39 kD protein of the Lyme bacterium, one band read as part of a Lyme disease immunoblot pattern.
- 39 KD (IgM) Band Shows whether your IgM antibodies react to the 39 kD protein of the Lyme bacterium, one band read as part of a Lyme disease immunoblot pattern.
- 41 KD (IgG) Band Shows whether your IgG antibodies react to the 41 kD protein of the Lyme bacterium, one band read as part of a Lyme disease immunoblot pattern.

- 45 KD (IgG) Band Shows whether your IgG antibodies react to the 45 kD protein of the Lyme bacterium, one band read as part of a Lyme disease immunoblot pattern.
- 58 KD (IgG) Band Shows whether your IgG antibodies react to the 58 kD protein of the Lyme bacterium, one band read as part of a Lyme disease immunoblot pattern.
- 66 KD (IgG) Band Shows whether your IgG antibodies react to the 66 kD protein of the Lyme bacterium, one band read as part of a Lyme disease immunoblot pattern.
- 93 KD (IgG) Band Shows whether your IgG antibodies react to the 93 kD protein of the Lyme bacterium, one band read as part of a Lyme disease immunoblot pattern.
- Lyme Disease Antibodies (IgG), Immunoblot The overall interpretation of an IgG Western blot (immunoblot) for Lyme disease, based on the pattern of antibody bands against Borrelia proteins.
- Lyme Disease Antibodies (IgM), Immunoblot The overall interpretation of an IgM Western blot (immunoblot) for Lyme disease, based on the pattern of antibody bands against Borrelia proteins, used mainly in early infection.
