ANCA testing was introduced in many laboratories throughout the world when it was recognized that a significant subset of patients with small vessel vasculopathies presented with such antibodies. Many laboratories developed and introduced in-house testing methods for antigen-specific ANCA detection complementary to indirect immune fluorescence screening. Such in-house tests have proven their merit in diagnosing vasculitis and were important to identify critical steps in the development of antigen-specific assays with high sensitivity and specificity. In the meantime various commercial assays became available for antigen-specific ANCA testing. Because of the high diagnostic accuracy of such assays it can be anticipated that commercial, antigen-specific tests will completely replace in-house testing for MPO- and PR3-ANCA. Furthermore, such tests will replace the need for IIF in the diagnostic workup of AAV. In this light it can be foreseen that the knowledge that underlies the development of in-house ANCA testing will gradually disseminate over time. Therefore we describe the current antigen-specific ANCA ELISAs (direct and capture) with the intention to maintain the knowledge and the identification of the critical steps in the development of robust assays.
