Yes it was a diagnosis by exclusion. I've been looking through the wavier guide and as far as I can tell it doesn't say anything about ITP except in regards to having a splenectomy, which I have not had. One thing that the flight surgeon wrote in my letter was that no amount of asymptomatic time would change their decision, and that no further evaluations would be necessary. I feel like they may have gotten stricter or more selective in the past few years, when did you get your waiver?
