[Detection of antibodies against Mycobacterium tuberculosis in patients with lung diseases by immunoenzyme analysis].

Diagnostic enzyme immunoassay kits were used for the examination of parallel tests of venous and capillary blood in 43 patients with nonspecific pulmonary diseases for the presence of antibodies to tuberculosis pathogen. The method of parallel tests has revealed that disregarding the site of blood collection (vein, finger) the EIA results are identical. Analysis sensitivity in tuberculosis patients varies within 30 and 86% in relation to the clinical activity of a tuberculosis process. Analysis specificity in tuberculosis patients is 3.4%.
