This article contains the results of the study of the exhaled breath condensate (EBC) by the means of laser correlation spectroscopy in patients with pulmonary tuberculosis before and after two months of treatment. It was found that the LC-spectra of the TB patients’ EBC differ significantly from those in healthy subjects and indicate a shift of metabolic processes, which in most cases is of catabolic type with moderate and high severity. After the treatment the nature of LC-spectra changes. The shifts are of the anabolic and mixed type, and the degree of their severity diminishes.
