I also have ET JAK2 diagnosed in June 2023 at age 72. Platelets were higher than normal for many years and doctors ignored because only 460-525. In 2017 was contemplating spinal surgery so went to hemo/oncologist and was given genetic testing but negative for MPN mutations but positive for Leiden Factor V. I didn't have surgery and again nothing done about platelets.
Then I was feeling fatigue and just off since having 3 covid vaccines in 2021 so went back to hemo/oncologist in 2023 because platelets were increasing to 600s. This time, I was JAK2 positive so diagnosed with ET. I had been taking 1 baby aspirin for 15 years so continued that daily dosage. I was not given any other meds for the ET even though at age 73 now I'm considered high risk. My oncologist wants to wait until platelets are over a million to start HU. But he did say with my Factor V blood disorder he will consider starting HU at 800 platelets. My last 3 month test was 673 so I'm just worrying, waiting and fatigued. My mother died from blood clots at age 56 after surgery but we didn't know that she obviously had ET until I was diagnosed. I have no history of blood clots but taking meds for high blood pressure and high cholesterol which are both controlled by meds. Wow, I need to print this for my medical records and show the oncologist next week.
