Hi, I am waiting for the results for jak2 tests. I have had results of over 450 in my platlets on routine blood tests going back 14 years some spiking up to 650 but my GP always said that was my normal. I have been to the doctors with pressure headaches coming and going for about the last 4 years. I recently saw a new GP at my practice due to being tired and wanted to see if it was menopause. My latest tests came back at high platelet again so he referred me to a hemotology consultant. He has sent off for the jak2 tests, I am wondering at the likelihood of essential thrombocytosis and what this will mean for me?
