Does IgA test for Lyme disease?
Specific IgA was detected in 59 of 152 serum samples (38.8%) from early Lyme disease patients. Approximately 50% of early Lyme disease patients who were seropositive for peptide-specific IgM and/or IgG were also seropositive for peptide-specific IgA.
At what stages of Lyme disease are the IgG and IgM antibodies elevated?
Types of Lyme Disease Tests IgM antibodies usually peak within a few weeks after an infection with Borrelia bacteria and start to collapse 4-6 months after infection. IgG antibodies are slower to develop, beginning to show 4-6 weeks after exposure and may peak 4-6 months after exposure.
Does positive IgG for lymes mean I have lymes?

What is B. burgdorferi IgG positive?
A positive result indicates that the immunoblot evaluation for B. burgdorferi antibody is consistent with the presence of antibody produced by patients in response to infection by B. burgdorferi and suggests the presence of Lyme disease.
What does a positive Lyme IgG IgM mean?
