Role of neutrophil- lymphocyte ratio and other routine hematological parameters in determining severity of disease in COVID-19 positive patients

ABSTRACT

Background: Coronavirus disease 2019 (COVID-19) is an ongoing global pandemic with second and third waves sweeping through different countries. Patients with severe disease have a poor prognosis and it is essential for us to identify these cases to initiate timely management. Neutrophil-to-lymphocyte ratio (NLR) has been documented to be higher in the severe patients. Aim: The aim is to assess the NLR and other routine hematological parameters in severe versus Non severe patients on admission to the hospital.
