18 KD (IgG) Band details
What 18 KD (IgG) Band shows
The 18 kD IgG band is one of several Borrelia burgdorferi proteins on a Lyme disease immunoblot, which checks which of the bacterium's proteins your antibodies react to. It is one of the bands counted under the CDC criteria for an IgG blot. A reactive band means your IgG antibodies bound this protein. On its own this can reflect past exposure, cross-reacting antibodies or a current infection, so it does not show Lyme disease by itself. Blots are read by the overall pattern of bands under CDC criteria, never by one band alone, and they follow a positive or equivocal screening test.
Tests that include 18 KD (IgG) Band
This test is used to detect antibodies antibodies to the bacterium Borrelia burgdorferi. This test is intended as the second step in testing serum samples found to have been equivocal or positive using an ELISA or IFA test.

- Lyme IgG Line Blot Interp. The overall interpretation of a Lyme disease IgG line blot, based on the pattern of antibody reactions to Borrelia proteins under CDC criteria.
- Lyme IgM Line Blot Interp. The overall interpretation of a Lyme disease IgM line blot, based on the pattern of antibody reactions to Borrelia proteins, used mainly in early infection.
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.
