[The diagnostic importance of determining tuberculosis antibodies by immunoenzyme analysis in exudative pleurisy].

High diagnostic value of EIA detection of antituberculous antibodies in recognition of tuberculous pleurisy was established after examination of 58 patients with pleural exudate of different origin (tuberculous, tumor, nonspecific). Tuberculous pleurisy was diagnosed using sonicate M. tuberculosis as the antigen. It is important to determine antituberculous antibodies simultaneously in blood serum and exudate because in such a way it becomes possible to raise the test specificity to 100% in high sensitivity (94.7%).
