[The immunological diagnosis of tuberculosis].

On the basis of literature review the article makes an appreciation of various methods for tuberculosis serological diagnostics. The authors mark a high information level of immunofermental analysis (IFA). 126 tuberculosis patients, 122 patients with non-tuberculosis etiology and 410 donors were examined with the aid of IFA (phosphide antigen). The min. diagnostic titer in pulmonary tuberculosis is 1:320, in nonpulmonary--1:160. The max. antigen titers in IFA (optical density unit of measurement) were in the cases of disseminated tuberculosis 1.32 0.12; the min.--in uterine tube tuberculosis--0.92 0.08. The titers of donors were 0.20 0.03, and of patients with non-tuberculosis diseases--0.25 0.04. IFA is recommended for practical application in tuberculosis and infectious clinics.
