PATIENTS LABORATORY TESTING OPTIMIZATION IN INFECTIOUS HOSPITAL UNDER THE PANDEMIA OF THE NEW CORONAVIRUS INFECTION COVID-19

Relevance. In order to prevent the spread of infection caused by the SARS-CoV-2 virus, in the spring of 2020, a number of hospitals were re-profiled in St. Petersburg toreceive patients with pulmonological pathology, including infectious etiology. In the period from March 30 to April 30, 2194 patients were admitted to St. Petersburg City Hospital №2, including 1211 (57%) with pneumonia of various etiologies, 508 (24%) patients with COVID-19 and 475 (22%) patients with other acute upper respiratory tract infections. The aim of this study was to evaluate the structure of the results of prescribed studies to optimize the laboratory service and assess the laboratory and examined patients profiles. Results structure assessment of a general blood tests showed the predominance of relative lymphocytopenia– in 51.9%; hemodilution in 57.9%; the average platelet volume was below the reference limits of 59.6%. Leukocytosis was observed in 46.5% and neutrophilia in 53.7%. Absolute monocy-tosiswas found in 45%. Tests analysis of the biochemical analytes concentrations showed elevated levels of: C-reactive protein – in 74.8%; glucose  in 73.9%; troponin I – in 75.6%; lactate dehydrogenase  in 63.4%; procalcitonin  in 55%; gamma-glutamyltranspeptidases – in 52%. Conclusion. To optimize the laboratory service of the hospital, the quantity of goods was increased by no more than 10% in government contracts concluded with suppliers of laboratory reagents, which made it possible to purchase additional supplies to ensure uninterrupted laboratory examination of patients in the infectious hospital in the conditions of the new coronavirus infection COVID-19.
