Objective Due to lack of comprehensive evaluation for various detection methods for antineutrophil cytoplasmic antibody (ANCA) in Chinese population, we evaluate the diagnostic performance of 12 established analysis methods in Chinese patients having granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA). Methods Sera were collected from 209 patients with GPA or MPA and 243 diseases controls from 15 centers. Twelve different reagents were employed for C-ANCA, P-ANCA, myeloperoxidase (MPO)-ANCA, and proteinase 3(PR3)-ANCA detection. The accuracy, sensitivity, and specificity of each method were analyzed. Results The accuracy of the two indirect immunofluorescence (IIF) and two line immunoassay (LIA) was 0.838 and 0.874, 0.869, and 0.862, respectively. The accuracy of the eight quantitative antigen-specific immunoassays was varied from 0.867 to 0.967. The sensitivity of ANCA-associated vasculitis (AAV) was 0.770 and 0.761 for the two IIF, 0.727 and 0.718 for the two LIAs, respectively. For the eight quantitative antigen-specific immunoassays, the sensitivity varied from 0.79 to 0.967. The specificity was 0.897 and 0.971 for the two IIF, 0.992 and 0.988 for the two LIAs, respectively. For the eight quantitative antigen-specific immunoassays, the specificity of AAV varied from 0.963 to 0.983. Conclusion For Chinese patients suspected of having GPA and MPA, both the first-generation enzyme-linked immunosorbent assay (ELISA) and high-quality antigen-specific immunoassay can be used to detect MPO-ANCA and PR3-ANCA alone, without the combined detection with IIF to have good diagnostic performance. The chemiluminescent immunoassay (CLIA) seems to be a method worth recommending.
