I'm guessing she's in early to mid-forties age range, which is young to me. And yes, she is definitely seeking out an immunologist with focus on the immunoglobins (not easy to find those that have interest in the IG category, but I know she is determined. She is very tolerant of my overkill with lab & imaging results over past 5 yrs. I only share key info, but she is appreciative rather than disinterested. I have appt tomorrow and actually can't wait (who looks forward to doctor appts? Lol)
