Study of neutrophil to lymphocyte ratio as a prognostic marker in COVID-19 infection-our experience at teritary care hospital

Abstract

Background: To evaluate the prognostic value of Neutrophil to lymphocyte ratio (NLR) in Covid -19 patients at our district area hospital/ Teritary care center. Methods: It is a prospective study from 1-8-2021 to 30-9-2021. Patients who presented with complaints of Fever, sore throat, body pains, cough, breathlessness, diarrhoea were evaluated at the triage area of the Hospital. Throat swab was taken and RT-PCR was done and only 200 confirmed cases were included in the study. Patient blood samples were collected and processed in SYSMAX 5 -part, Heamotology analyser in the Hospital Central Laboratory. The patients CBP was processed in the laboratory NLR value calculated and tabulated. Results: Out of 200 cases number of Males were 145(72.5%) more compared to the female were 55(27.5%), with NLR value 1.0-3.9 in74 cases(37%) ,4.0- 6.9 in 63 cases (33%) , 7.0 – 9.9 in 25 cases (12.5%), 10-12.9 in 17 (8.5%) cases , 13-15.9 7 cases(3.5%), 16 -18.9 3 cases(1.5%) ,19-21.9 9 cases(4.5%) ,22-24.9 0 cases, 25-27.9 0 cases , 28-30.9 2 cases ( 1%). Conclusion: NLR Value more than 3.5 found to be significant and it is correlating with the patients symptoms.
