LABORATORY ASSESSMENT OF INFLAMMATORY BIOMARKERS IN PULMONARY DISEASES

Abstract

nflammatory lung diseases are among the most common causes of 
morbidity and mortality and are accompanied by the development of systemic and local 
inflammatory responses. This article reviews the main inflammatory markers used in 
the laboratory diagnosis of lung diseases and discusses their diagnostic and prognostic 
significance. Particular attention is given to indicators such as C-reactive protein, 
procalcitonin, interleukins, ferritin, and parameters of the complete blood count. The 
role of laboratory investigations in the differential diagnosis of bacterial and viral 
infections, assessment of inflammatory activity, monitoring of treatment effectiveness, 
and prediction of disease course is demonstrated. A comprehensive laboratory 
approach facilitates timely diagnosis, rational selection of therapeutic strategies, and 
improvement of clinical outcomes in patients with lung diseases.
