well the most frustrating part is waiting to get started fixing things. I have Iron saturation of 6% get iron goes up to 30 and back down to 6 by the next week makes me crazy and until they confirm the diagnosis bacause of the dry tap the BMB was repeated. I have not heard back yet about the Jak2 yet. Which test would it be on. I make them give me copies of everything. I am waiting for MD Anderson to re-evaluate the first biopsy and compare to the second also a dry tap. I just want them to get a confirmed diagnosis. Did you get one from the first BMB?
