Hello All, I am doing research to find a clinic that will accept patients without a bone marrow biopsy. My allergist and I tried the Brigham Hospital in MA, but they were super unhelpful in the process of getting in. Even the staff wouldn't talk with my doc! Its such a frustrating process to get in where there is experienced people who really can speak on this disorder. Does anyone have suggestions of places they have tried or tactics in speaking with specialized places? What does Mayo offer in terms of this?
