8220 – CytoBead® ANA 2
Intended Purpose
The CytoBead® ANA 2 is an immunofluorescence assay (IFA) for the qualitative and semi-quantitative determination IgG antibodies in human serum against nuclear and cytoplasmic antigens (dsDNA, Scl-70, SS-A/Ro60, SS-A/Ro52, SS-B, Jo-1, Sm, Sm/RNP). The CytoBead® ANA 2 is is intended as an aid in the diagnosis of systemic autoimmune diseases 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 autoantibodies in patient sample, e.g. plasma and serum, is well established and plays an essential role in the diagnosis of systemic autoimmune diseases. The use of Hep-2 cells in immunofluorescence assay offers a very sensitive screening approach to detect antinuclear antibodies (ANA) directed against components of the cell nucleus. By identifying the staining patterns on HEp-2 cells, the identification of the antigen targeted by ANA and the associated autoimmune disorders is achieved.
