Hematological indicators for lung damage caused by COVID-19 infection

During the pandemic of a new coronavirus infection one of the most serious complications is pneumonia. When entering a specialized pulmonology Department, the presence of pneumonia is confirmed by computed tomography (CT), the etiology is confirmed by the detection of SARS-CoV-2 RNA by PCR, the article analyzes the indicators of blood analysis when patients are admitted to the hospital. All admitted patients were divided into 2 groups. Group 1 of the study - with a new coronavirus infection Covid-19, confirmed by the detection of PCR-RNA SARS-CoV-2 (n=27). Group 2 consisted of 65 patients (70.7%) with lung tissue damage characteristic of Covid-19 according to CT, who had a negative analysis of PCR-RNA SARS-CoV-2. Statistically significant deviations were shown in a decrease in the percentage and absolute content of lymphocytes, monocytes and platelets, and an increase in neutrophils. The comparative analysis in the groups with positive and negative PCR analysis for the detection of SARS-CoV-2 RNA showed no statistically significant differences. It can be assumed that with the similarity of clinical manifestations and CT-data, a negative result of PCR-RNA SARS-CoV-2 can be diagnosed as «lung damage caused by COVID-19 infection».
