question: I have an elevated platelet count of 542.....my mother was recently diagnosed with multiple myeloma and is now in remission and my younger sister was diagnosed with RA at age 40. I am a diabetic also. Should I be concerned? Physician says I need to see a Hematologist but I don t want to look for trouble. Is my level high enough to warrant having testing and if so, what should I be looking for? Also, TSH is now elevated at 4.462. This was normal 6 months ago.
