Thanks all for your responses. I had to look-up the ASU information...brain fog is getting really bad.
'The study design I created this past Spring was simple: an immunosignature is a snapshot of all your antibodies at the moment you take a blood sample. You send me your blood, I create your personal immunosignature, and I then compare your signature against other people who were diagnosed with either fibromyalgia, ME/CFS, or healthy controls. There are 125,000 different measurements (peptides) that I examine. Out of those 125,000 measurements, only a few are common to a disease. The rest represent all of your previous environmental exposures, illnesses, vaccines, and allergies. Those are independent of your CFS or FM state and are ignored. The few measurements that correlate to your CFS or FM status are compared, person by person, to create the map you see. Your number is next to your dot, and your dot represents where your signature lies relative to everyone else in the study. I made the map as big as I could, but since the CFS group was large and had so many people, you might not see your number, or your number is on top of another number. If you don’t see yours, it’s likely right in the middle of the cluster of magenta dots. The controls tended to cluster near the center, and many people clustered near the control group. That may indicate the severity or duration of your disease, or how many ME/CFS or FM antibodies you have relative to everyone else. Some people who were listed as FM were closer to the CFS group and vice versa. That may indicate some cross-reactivity or lack of specificity of my test. Either way, if this were a diagnostic, you would either get an ‘indeterminate' result, or a dual positive result. I don’t know how to interpret this result in terms of a commercial diagnostic yet, but if I were to present my results to the FDA, I would suggest a blood test that consists of several donations over 3-6 months. The signatures change a little over time, and it moves as your disease progresses or wanes. Those few extra time points would make the diagnostic more precise. A single time-point may be too coarse for accuracy.'
