I have a hematologist appt. on Monday. I have been having elevated platelets for about 5 years now. They were going down, but last summer started rising some. My platelets are now at 492,000. They were 469,000 last August. I saw that normal platelet count according to the CDC & John Hopkins tops out at 450,000, but my Gynecologist (where I had my CDC) says 350,000 tops normal. My white blood cells are also a little elevated at 11.8. I don t know why the WBC would be high now unless it s from my gallbladder. I have occasional gallbladder attackS which I now vomit with. An ultrasound of my gallbladder showed small stones 2-3 years ago. I m getting terrified that I have some kind of blood cancer, because I ve been researching. (Yeah probably not a good idea.) I really hope it s all from my gallbladder since I am having problems with it, but not as long as the platelets have been elevated. but I m about to freak. What info can you give me until I see the hematologist? Can gallbladder issues cause elevated platelets & WBC levels? What testing can I expect from the hematologist? (The thought of a bone marrow aspiration or biopsy terrifies me. Would this be a routine test?) Thank you for any information.
