Laboratory indicators in patients with non-severe new coronavirus infection COVID-19

Abstract

The article presents literature data on changes in labo-ratory parameters in new coronavirus infection COVID-19 and the results of our own researches. It was found that in the first three days after hospitalization, most patients had normocytosis, a normal number of lymphocytes. In the mild form, there were slightly more people with normal or with an increased number of leukocytes, granulocytes, but in moderate course, leukopenia, lymphopenia, granulocytosis and granulocytopenia, thrombocytosis, thrombocytopenia were registered more often. At the same time, in the mild form, there were more patients with an increased number of band neutrophils. In mild course, there were no individuals with an increased number of band neutrophils after 3 days in the hospital. Leukocytosis, lymphopenia, granulocytosis were no longer detected after 6 days in the hospital; during this period, the number of patients with leukopenia, thrombocytopenia also decreased significantly, most people had normocytosis. In patients with moderate-to-severe course, leukocytosis and leukopenia were observed for a longer period than with the mild course, even after 10 days in hospital. Most patients had normocytosis. By the sixth day of hospital stay, there were more individuals with granulocytosis (no such patients were registered at a later date), with an increased number of band neutrophils. After 6 days, there was greater number of patients with lymphocytosis, thrombocytosis and lymphocytopenia.
