ANCA test has diagnostic significance on AAV. The Immunofluorescence Assay (IFA) usually has a perinuclear staining pattern (PANCA), and Enzyme-Linked Immuno Sorbent Assays (ELISA) detect antibodies to Myeloperoxidase (MPO-ANCA) in MPA. Kidney involvement is noted in approximately 80-100 percent of patients with MPA cases, and the clinic spectrum range from microscopic hematuria to severe kidney injury with dialysis requirement. Pulmonary involvement is noted in approximately 25-55 percent of patients with MPA. Several observations and presumptions have been noted about TIN accompanying crescentic glomerulonephritis. This diversity may be considered as only a simple histological elaboration. However, it is a significant clinical entity for guiding the treatment.
