Lyme Disease IgM antibodies usually appear 1-2 weeks after an initial exposure and return to normal after about 6 to 8 weeks. IgG antibodies are detectable in most people 4-6 weeks after exposure but may be detectable sooner in some people. IgG antibodies may persist indefinitely.

IgG will frequently cause in vivo hemolysis due to antibody coating the red blood cells.
