[Clinical importance of laboratory tests in rheumatology].

Knowledge of mechanisms of rheumatic diseases has a continuing influence on the introduction of many laboratory tests to be used for establishing diagnosis or monitoring the activity of rheumatic disease. In the article presented are autoantibodies characteristic for distinct inflammatory rheumatic diseases, the role of serum complement activity, immune complexes, HLA-typing as well as other laboratory parameters needed for the diagnosis of rheumatic disease. The methods of synovial fluid analysis are described. Presented are laboratory investigations used by rheumatologists for the evaluation of activity of inflammatory rheumatic diseases and successful treatment together with investigations necessary for the evaluation of side-effects of treatment.
