Platelets are too high: What can be done to find root cause?

Patty, when my platelet count rose slowly & steadily over several years I was very worried about the possible cause (inflammation? infection? ovarian cancer?). When it reached 400-500 about 6 months ago, genetic testing showed the JAK2 mutation. I believe that's present in many (maybe most?) ET cases & that (I think) was likely the cause. Started taking one 500 HU a day & the numbers are now in the normal range -- hoping they stay there.

I have been on this medication for over 3 years. Still in mid 600. I was taking one 2 a week and now up to 3. We will see if this has helped when I have blood work later this month.

Thanks for info

I also have the JAK2 mutation as does my brother. My brother could not tolerate the side effects of hydroxyurea but I can. My brother is taking a different medication for the JAK2 mutation but not sure what it happens to be. My last blood draw revealed a 408 blood platelet count and my first platelet count last a year ago was 1 million.
