The subject of this teaching abstract is the diagnosis of tuberculosis, specifically focusing on the symptomatology of pulmonary tuberculosis and laboratory diagnostics. The purpose is to educate medical practitioners on the early detection of pulmonary tuberculosis among the population. The case study emphasizes the importance of primary care settings in minimizing clinical errors during patient examination and analyzing laboratory and radiologic results for accurate diagnosis. Expected learning outcomes include skills in drawing up examination plans, assessing clinical symptoms, interpreting laboratory results, and understanding radiological methods. To successfully solve the case, students need knowledge of the primary health care network's role in combating tuberculosis, examination algorithms, clinical symptoms, laboratory and radiological diagnostic methods, and TB diagnostic techniques.
