Many early symptoms of Granulomatosis with polyangiitis (Wegener's) are similar to those of milder and more common respiratory problems. As a result, the average person with Granulomatosis with polyangiitis (Wegener's) often has symptoms for months before the correct diagnosis is made.

These tests also help to check for other illnesses that may cause symptoms similar to Granulomatosis with polyangiitis (Wegener's).
The only way to confirm this diagnosis is to have a biopsy. Tissue is taken from an affected organ. It is then examined under a microscope to check for granulomas and areas of inflammation.
