[Microbiological blood studies in the diagnosis of tuberculosis in adolescents]
Abstract:
Luminescence bacterioscopy of capillary blood has been found to be an additional rapid laboratory method that verifies a clinical diagnosis in cases of negative sputum bacterioscopic tests in 48.8% of the adolescent patients. The Boy luminescence microscopy shows that in adolescent tuberculosis patients, Mycobacteria are significantly more frequently present in the capillary blood (72.4%) than in the sputum (30.9%) and bronchial washes (34.8%). The detection of Mycobacteria in the capillary blood has been evidenced by cultural tests of some venous blood samples in the BACTEC 460 TB system.

Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
