I just hope this isn't preventing you from getting the correct treatment/relief. I would imagine it does and understand your frustration. I have the exact opposite situation. High hemoglobin and hematocrit, low EPO but no JAK2 mutation. According to a DNA report that I just ran the other night, I do have variants in my JAK2 genes so I emailed my hematologist to ask if that would be helpful in a diagnosis. I'm pretty sure he doesn't like me much because I am VERY proactive in my healthcare. Have to be. I'm just a number to these doctors.
