Title: ROLE OF HEMATOLOGICAL PARAMETERS IN EARLY DIAGNOSIS OF COVID-19 IN A TERTIARY CARE CENTRE
Abstract: Aim: To evaluate the role of biomarkers from blood samples of COVID-19 patients admitted in Index Medical College Hospital & R.C.
 Material & Methods: Hematological parameters such as Neutrophil lymphocyte ratio (NLR), Platelet lymphocyte ratio (PLR) & Systemic Inflammatory Index (SII) were studied in RT-PCR positive patients to evaluate the utility of these parameters for early diagnosis of COVID-19.
 Results: The study showed that there was statistically significant difference in test groups in reference to Neutrophil lymphocyte ratio (NLR) & SII values (p<0.05). But no statistically significant difference was observed between test groups in reference to Platelet lymphocyte ratio (PLR) values (p>0.05).
 Conclusion: Leukocyte, Neutrophil, NLR & SII values can be used in the early diagnosis of COVID-19.
 Keywords: NLR, SII, Leukocyte, Neutrophil
