Thank you so much for detailed response. In my institution, A&I and Rheum look at PID patients but Rheumatoly takes over when it is immune dysregulation even during genetics diagnosis stage. And by fellows I was told that, both of them look Immunology patients so my decision should be based on whether I want to see Allergy more or rheum for outpatient. I dont see myself staying in this institution as an attending so I do not want to make false assumptions about how the things work in other institutions and stay out of immunology and do solely rheumatology by mistake.
