41 KD (IgG) Band details

What 41 KD (IgG) Band shows

The 41 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 flagellin, a protein from the bacterium's tail-like flagella. 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. Because flagellin resembles proteins in many other bacteria, this band is often reactive in people who have never had 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.
