Hi, I've just come back from a visit to a Rheumatologist. Having braced myself for the usual invalidating response, he said immediately that there were some very strange things in my blood that he wanted to get to the bottom of. He said I had very high platelet levels in particular and that there were a sign of ongoing immune activity, and not characteristic of ME. He said there were no indicators of autoimmune illness - the features were sort of the opposite of what he sees in RA, MS - but has referred me to an infectious diseases person. I looked here on PR, and most posters mention low, not high platelets. Anyone know what high platelets might mean?
