An antineutrophil cytoplasmic antibodies (ANCA) test is a blood test that checks for proteins your immune system makes to fight germs. ... Indirect immunofluorescence (IIF).

Anti-neutrophil cytoplasmic antibodies (ANCAs), such as those directed towards proteinase 3 (PR3) and myeloperoxidase (MPO), are associated with a distinct form of small-vessel vasculitis, known ...

Screening for the presence of antineutrophil cytoplasmic antibodies (ANCAs) is a valuable tool in the serological evaluation of systemic vasculitis disorders. In this article, Csernok and Moosig ...

ANCAs can be detected using techniques such as indirect immunofluorescence microscopy. This can visualize patterns which are either cytoplasmic, and are designated as c-ANCA, or perinuclear ...

In 1990, Koderisch et al. were the first to report the presence of 'false-positive' ANCAs by indirect immunofluorescence and anti-myeloperoxidase antibodies by enzyme-linked immunosorbent assay in ...

The antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (eg, ANCA vasculitis) are a heterogeneous group of rare, life-threatening, immune-mediated disorders that are characterized ...

The IIF assay also detected ANCA prevalence in 3.6% mild COVID-19 patients during acute illness as compared to 2.4% healthy individuals. Contrastingly, a significantly higher ANCA prevalence in 19 ...

The discovery of "complementary" antibodies against plasminogen in patients with blood vessel inflammation caused by anti-neutrophil cytoplasmic autoantibodies (ANCAs) may lead to new approaches ...
