Two years ago my initial lyme test was negative, but I was diagnosed with lyme on the basis of my symptoms and the bulls eye rash.

A year later, they did the lyme test again -- for the doc, it was out of curiosity to see if it would now be a positive; for me, I was having some of the same symptoms I had when initially diagnosed, and I thought it might be from lyme (but of course, they didn't think that).

The western blot IgG was negative, but the IgM was positive. The docs thought that was strange that I didn't have any IgG -- so, they said I must have been bitten again. They gave me their standard 3 weeks 200 mg doxy regime, and then repeated the test.

Lo and behold, same results! (no surprise to me) They had the lab repeat the test on the same blood...same result.

I guess my biggest question is, why would I NOT have any IgG so long after an initial infection, BUT a positive IgM? I know some people get a completely negative test result, but I don't think I've heard of this kind of test result before? Also, I've had a positive ANA for many many years -- which is now negative for the first time. Is this a good sign, or bad?

There is a possibility that I did actually get bitten again as we have an ongoing problem in our yard with ticks -- although I am highly vigilant about checking myself for ticks and basically avoid my yard completely! But, shouldn't I have some IgG ?
