Hi there, I can't speak for sure about who Dr Grattan will take on the NHS, though more recently it has seemed to be mastocytosis patients on the NHS. I believe that one criteria for private patients is that they need to have skin involvement since he is a dermatologist, but I would encourage you to give it a try and see if he will take you, if you're in a position to pay. For referrals from outside London on the NHS I suppose you can see if your doctor will refer you but it does take longer on the NHS and if you aren't yet diagnosed it might be harder for them to accept you.
