Neutrophils to Lymphocytes Ratio and the Prognosisof the COVID-19 Patients

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a new pandemic virus, global concern, and has threatened human health. This virus binds to the Angiotensin-Converting Enzyme (ACE2) that expressed on different cells, especially alveolar cells. So can enter lung cells causes respiratory syndromes. In Disease 2019 (COVID-19) caused by SARS-CoV-2, failure, acute inflammation main cause of death. According several reports, multiple factors, such as Neutrophils Lymphocytes Ratio (NLR) have prognostic potentials in COVID-19. study aims review this parameter better prediction about condition patients their treatments. review, NLR ratio related innate immune responses be helpful discrimination severe from non-severe cases COVID-19 patients.
