[Clinical and laboratory diagnosis of primary tuberculosis of respiratory organs in adults].

Comprehensive clinical, X-ray, and laboratory studies were made of 495 patients with primary tuberculosis of respiratory tuberculosis whose age was over 18 years. Tuberculosis of intrathoracic lymph nodes (a tumorous form), infiltrative tuberculosis at preroot and lower lobar sites), and exudative pleurisy were prevalent in the clinical structure of primary forms of a specific process. The highest morbidity was observed in the age group of 20-25 years. Tuberculin tests were positive in 95.1% of cases, they being hyperergic in 10.9% and negative and nuclear only in 4.9%. Sputum tests for altered forms of tuberculosis agents enhance diagnostic verification by 16%. The informative value of a complex of clinical and X-ray examinations in the diagnosis of primary respiratory tuberculosis in adults ranges from 47.4 to 79.6% with immunoassay, and 28.3 to 77.5 with biochemical tests.
