Changes in Laboratory Biomarkes as Mortality Indicator in Covid-19 Patients

Abstract
This study aims to investigate changes in laboratory biomarkers in COVID-19 patients who survived compared to non-survivor patients. Retrospective studies of observational studies were conducted on patients confirmed COVID-19 with RT-PCR technique. Positive COVID-19 patients will be grouped into two groups, namely survivor (S) and non-survivor (NS) patients. At the time of hospital admission, eosinophil counts were lower in NS than in the S patients (p< 0.05). In addition, CRP levels were significantly higher in NS cases than cases S patients (p< 0.05). At the time of hospital discharge, basophil, eosinophil, neutrophil, and lymphocyte counts were lower in the NS compared with the S group (p< 0.05). Thus, it was concluded that the decrease in eosinophils followed by a decrease in basophils, neutrophils, and lymphocytes could be the initial predictors for the death of COVID-19 patients. Therefore, regular monitoring with routine hematological analysis is very important for the care of COVID-19 patients. Keywords - Coronavirus; Survivor; Non-Survivor; Laboratory Biomarker
