Re: band 66.......
I was very curious about this thread since I have always been positive at band 66, so I called Igenex and spoke to Dr. H. Yes, band 66 has been associated with Erlichiosis but it is also a non-specific Lyme band. I have also seen band 45 associated with Erlichiosis.
When they say non-specific Lyme band I think they mean that they know it has something to do with Bb, but they are not quite sure if it is an outer surface protein or what have you.
The bands that are specific just to Bb are 23-25, 31, 34, 39, 93. If you test positive (even weakly to any one of those, then you have been exposed to Bb and your body is recognizing it) Many LLMD's feel that a positive or even indeterminate at even one of these 5 bands is diagnostic.
Take care all-
