I tested negative, and have continued to test negative for Lyme disease on the IgeneX western blot and PCR. However, I was highly suspect of having lyme disease since I had four active co-infections, an NK CD57 of 7, and a C4a of 13000. I also lived in Lyme endemic regions (including Lyme CT) and was constantly in the woods. My doctor told me that I probably have Lyme, but people with the worst cases usually test negative. After treatment begins and they "stir things up" people start testing positive. Does anyone have any experience with this? How long did it take before you started testing positive? Thanks.
