"With most infections, your immune system first forms IgM antibodies, then in about 2 to 4 weeks, you see IgG antibodies. In some infections, IgG antibodies may be detectable for years.
Because Borrelia burgdorferi is a chronic persistent infection that may last for decades, you would think patients with chronic symptoms would have positive IgG Western blots.
But actually, more IgM blots are positive in chronic borreliosis than IgG. Every time Borrelia burgdorferi reproduces itself, it may stimulate the immune system to form new IgM antibodies.
Some patients have both IgG and IgM blots positive. But if either the IgG or IgM blot is positive, overall it is a positive result.
Response to antibiotics is the same if either is positive, or both."
also from the above link...
" Band 83: This is the DNA or genetic material of Borrelia burgdorferi. It is the same thing as the 93, based upon the medical literature. But laboratories vary in assigning significance to the 83 versus the 93.
Band 93: The DNA or genetic material of Borrelia burgdorferi."
You can't argue with DNA!!!
Print out the information on the western blot testing and read it several times. Then it will all make sense to you!
