23 KD (IgG) Band details

What 23 KD (IgG) Band shows

The 23 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. 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 IgG blot. A reactive band means your IgG antibodies bound this protein. This can reflect past or current exposure, but a single band does not show Lyme disease. 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.
