<p><strong>Materials and methods.</strong> A one-stage comparative study involved 123 patients hospitalized in a hospital with a confirmed diagnosis of community-acquired pneumonia. The mean age of the patients was 49.521.0 (<em>MSD</em>) years. On the first day of hospitalization, all patients underwent a general clinical examination, chest x-ray, and a plasma procalcitonin level was determined using a semi-quantitative rapid test.</p>
<p><strong>Results.</strong> Indicators of a new semi-quantitative rapid test for procalcitonin of at least 2 ng/ml are directly related to laboratory and instrumental indicators reflecting the severity of community-acquired pneumonia, namely, the severity of respiratory failure (p=0.001), respiratory rate (<em>p</em>=0.001), and heart rate contractions (<em>p</em>=0.001), systolic blood pressure (<em>p</em>=0.025), oxygen saturation (<em>p</em>=0,001), erythrocyte sedimentation rate (<em>p</em>=0.021), fibrinogen (<em>p</em>=0.003) and high CRB-65 scores (<em>p</em>=0.001). They are also associated with multisegmental community-acquired pneumonia (<sup>2</sup>=4.7; <em>p</em>=0.030) and complications of this disease, such as hydrothorax (<em>p</em>=0.029) and death (<sup>2</sup>=22.1; <em>p</em>=0.001).</p>
<p><strong>Conclusion.</strong> Using a new semi-quantitative rapid test for procalcitonin allows you to optimize the diagnosis of complications of community-acquired pneumonia and determine the high risk of multisegmental pneumonia.</p>multisegmental community-acquired pneumoniadiagnosisprocalcitoninbiomarkersprognosisполисегментарная внебольничная пневмониядиагностикапрокальцитонинбиомаркерыпрогноз[Ramirez JA, Wiemken TL, Peyrani P, et al.
