[Diagnostic significance of assaying glycoproteins, immunoglobulins, complement fractions and carcinoembryonic antigen in pleural and peritoneal exudates and transudates].

The Authors have determinated the concentration of some glicoproteins, IgG, IgA and IgM, C3 and C4 and CEA in 61 peritoneal and pleuric effusions, of various aethiology. Results obtained for glicoproteins and C3 appear to have a diagnostic value in distinguishing inflammatory and neoplastic effusions from non-inflammatory and non-neoplastic forms. A greater diagnostic value can be attributed to the results of the CEA which is constantly and almost exclusively increased in neoplastic effusions.
