Hello, I am new to this forum, so if this is the wrong place, please advise. I recently had a series of testing done for chronic Lyme and those tests came back inconclusive. Of concern was my C4a and C3a. My C3a was 409 with the reference range of 0-489 and my C4a was 44,480 with a reference range of 0-2890. My doctor suspects mold and wants me to do a charcoal regime. I am not sure what the right thing to do is. I have been treated for CFS and fibromyalgia for about 10 years. No one else in my home is sick, with the exception of colds and occasional sinus problems that seemingly stems from living in the Midwest near a corn sweetener and soybean plants. Any information would be helpful.
