23 KD (IgM) Band details
What 23 KD (IgM) Band shows
The 23 kD IgM 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. This band corresponds to outer surface protein C (OspC), which the bacterium produces early in infection. It is one of the bands counted under the CDC criteria for an IgM blot. A reactive band means your IgM antibodies bound this protein. IgM antibodies are the first type made after an infection, so this can fit recent exposure, but one band does not show Lyme disease. Blots are read by the band pattern under CDC criteria, never one band alone, and IgM results are mainly useful in the first weeks of infection.
Tests that include 23 KD (IgM) 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.
- 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.

- 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.

- 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 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.
