He told me that IGM bands were only reactive in the first month or two of lyme sickness. He said someone who has been sick for a year or more would switch to reactive IGG bands and the IGM's would be okay. I only had one IGG that was reactive. I have had something called antiphospholipid antibody syndrome since around 1992 and he thinks that is the reason for my positive IGM bands. There just so happens to be a seminar in the city next door to mine tomorrow and I am going to try and show it to the LLMD that will be there. Wish me luck with that one. Other than that I will have my muscle biopsy soon and that will be one more stone overturned. I really hope both of our biopsies show something. Leslie
