У больных определяли антинуклеарные антитела в реакции непрямой иммунофлюоресценции, методами иммуноферментного анализа и иммуноблоттинга. Результаты всех использованных лабораторных тестов коррелировали друг с другом, что свидетельствует об удовлетворительной сопоставимости различных лабораторных методов. Наиболее чувствительным методом выявления антинуклеарных антител является реакция непрямой иммунофлюоресценции, что определяет актуальность ее использования для скрининга аутоиммунных заболеваний соединительной ткани. Сопоставление типов свечения в иммунофлюоресцентном тесте и результатов иммуноблоттинга показало, что для каждого типа свечения характерен определенный набор аутоантител, выявляемых методом иммуноблоттинга. Однако одни и те же антитела могут обнаруживаться при различных типах флюоресценции, что затрудняет однозначную интерпретацию результатов иммунофлюоресцентного теста. Наиболее часто выявляемыми аутоантителами оказались антитела к Ro-52, которые выявлялись при всех типах флюоресценции, а также при отсутствии таковой.</p></abstract><trans-abstract xml:lang="en"><p>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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>антинуклеарные антитела</kwd><kwd>аутоиммунные заболевания</kwd></kwd-group><kwd-group xml:lang="en"><kwd>autoantibodies</kwd><kwd>autoimmune diseases</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Лапин С.В., Тотолян А.А.
