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.

Background: Haematological parameters have an important role in the early detection of the COVID19 disease. This study is aimed to study the hematological severity markers of COVID19 infected patients in first wave versus second wave in a tertiary care centre.  Methods: This is a retrospective study done in government medical college/government general hospital, Suryapet. We collected the information regarding patient’s data from hospital records who were admitted in the hospital during first wave in September 2020 and compared it with the patients admitted in the second wave in  May 2021. Results: In our study, a total of 341 patients with COVID19 infection admitted in our hospital were included. 136patients were admitted in first wave and 205 patients were admitted in the second wave. Out of 136 patients in first wave, 95 were admitted in non-ICU ward and 41 were included in ICU ward. We found that there is increased Absolute Neutrophil count, decreased Absolute Lymphocyte count and Platelet counts in second wave ICU patients. Conclusion: We conclude that based on the haematological parameters disease severity was more pronounced in second wave, especially ICU patients than first wave.
