A Study of Neutrophil to Lymphocyte Ratio (NLR), Platelet to Lymphocyte Ratio (PLR), Absolute Lymphocyte Count (ALC) in COVID-19 Infected Patient in Teriary Care Centre in South-West Bihar

ABSTRACT

Introduction: COVID-19 is caused by novel severe acute respiratorysyndrome corona virus (SARS-CoV-2). Which first appeared inDecember 2019 in Wuhan, china, China on December 31, 2019,reported on a cluster of cases suffering from severe pneumonia ofunknown cause in Wuhan, Hubei province. Two Week later new virusvariant called sever acute respiratory corona virus syndrome (SARSCoV-2) Caused by Corona Virus disease 2019 (covid-19) was foundin an outbreak in Wuhan china and spread to the rest of the world Thefirst case of COVID-19 in India was reported on 30 january 2020 inkerala.Aims &Objectives: To Profile the Neutrophil to Lymphocyte Ratio(NLR), Platelet to Lymphocyte Ratio (PLR), Absolute LymphocyteCount (ALC) in Covid-19 Infected Patient.Materials &Methods: Retrospective study of hematologicalparameter of covid19 positive patient during (01 May 2021-31 May2021).Result: In 100 covid-19 positive patientsin which, 62(62%)were maleand 38(38%) were Female,with age range from 5 months to 80 yearswith 50% patients above 50 years,there was increase in NLR in all100 patients and decrease ALCin75.Conclusions: Majority of the patients are elderly and there was malepredominancein was increase in NLR in all 100 patients and decreaseALCin75.
