What the hell difference does it make where it is detected? If you have Wegener's and you have nose symptoms that do not respond to antibiotics, then you have Wegener's in the nose. but so what? There is no different treatment for this than if it were to present anywhere else. It is kidneys, heart and lungs that are the major risks even though the sinus problems can be very unpleasant. I just don't see the purpose in seeking out this information at your risk.
