Lymphocyte Ratio, Leucocyte Count and D-Dimer in Early Prognostication of Covid-19 Patients: A Prospective Study

COVID-19 was declared as a global pandemic by the year 2020 , caused by the severe acute respiratory syndrome coronavirus – 2 (SARS-CoV-2) strain which claimed the lives of millions globally. Hospitals have been burdened with the admissions of the disease and the categorization of patients as per clinical severity for the treatment. Early detection of severity prognostic biomarkers will aid in the decreased morbidity and mortality of diseased patients undergoing treatment. Novel biomarkers like neutrophil to lymphocyte ratio, D-dimer and Leukocyte count are useful for the categorization of these patients and to assess their disease severity. These markers individually are used as inammatory markers and markers of thrombotic events. The assessment of utility of these biomarkers would be benecial for screening , better management , and reduction of serious complications for pandemics like COVID-19 . All age groups are affected by the pandemic , co-morbidities in addition increase the severity of the disease.
