APPLICATION OF DIFFERENT LABORATORY METHODS FOR ANTINUCLEAR AUTOANTIBODIES INVESTIGATION IN PATIENTS WITH AUTOIMMUNE CONNECTIVE TISSUE DISEASES
Abstract
1222 patients with suspicion of different autoimmune connective tissue diseases are investigated. Antinuclear antibodies by indirect immunofluorescence reaction, by methods of ELISA and immunoblotting were determined. Laboratory tests results correlated with each other that testifies to satisfactory comparability of different laboratory methods. The most sensitive method for detection of antinuclear antibodies is indirect immunofluorescence. This is a preferable method for screening of autoimmune connective tissue diseases. At comparison of luminescence types in immunofluorescence test and results of immunoblotting was shown that for each type of a luminescence the set of antibody, revealed by immunoblotting, was characteristic. However, the same antibodies can be found in various types of fluorescence that complicates unequivocal interpretation of immunofluorescence test results. Antibodies to Ro-52 were most often found in all types of fluorescence, and also in the absence of that.
