8063 – CytoBead® ANCA
Intended Purpose
The CytoBead® ANCA is an immunofluorescence assay (IFA) for the qualitative and semi-quantitative determination of IgG antibodies in human serum against neutrophil cytoplasmic antigens (ANCA) and the glomerular basal membrane (GBM). The CytoBead® ANCA is is intended as an aid in the diagnosis of systemic vasculitis as well as autoimmune renal disorders in conjunction with other clinical and laboratory findings. The immunoassay is designed for manual professional in vitro diagnostic use.
Diagnostic Relevance
The appearance of autoantibodies directed against components of the cell nucleus are characteristic features of systemic autoimmune diseases, especially; systemic lupus erythematosus (SLE), Sjögren’s syndrome, progressive systemic sclerosis (PSS), mixed connective tissue disease (MCTD), rheumatoid arthritis (RA) and dermatomyositis.
The detection of auto-antibodies in patient sample, e.g. plasma and serum, is well established and plays an essential role in the diagnosis of systemic autoimmune diseases. Cytobead ANCA is used for the differential diagnosis of ANCA associated vasculitis and systemic vasculitis (Granulomatosis with Polyangiitis, Microscopic Polyangiitis, Eosinophilic Granulomatosis with Polyangiitis) as well as autoimmune renal disorders (Goodpasture-syndrome).
