Hi, I am new here. I have just received test results showing a negative IgG and a positive IgM for CPN. The IgM is a titer of 1:80 (negative cut off is 1:10). I have CFS-ME and an SCL-70 marker for potential scleroderma with lung involvement. Not going to list all my diagnises and symptoms right now but they would of course fit with a CPN diagnosis, but also could fit lyme or the possibly viral (EBV and HHV-6 are potential probems as well).
