Comparative Evaluation of WBC Scattergram, Histogram and Platelet Indices in COVID and Non Covid Patients: An Observational Study

ABSTRACT

Introduction: Coronavirus disease 2019 (COVID-19) is extremelytransmissible infectious disease caused by severe acute respiratorysyndrome coronavirus 2 (SARS-CoV-2). Detection of Coronavirus byRT-PCR is the primary method which requires expert skills. RT-PCRtest is not widely available in all the laboratories. Cost effectivescreening of COVID-19 could be possible with the automated analysers which may provide a hint for early diagnosis. Histogramanalysis is neglected part of the automated haemogram when interpreted efficaciously has noteworthy capacity to contribute fordiagnostically pertinent information before higher level investigationsare requested.Aims &Objectives: The aim of this study is to evaluate RBC andplatelet histogram graphic patterns, WBC scattergram alongwithplatelet indices in 500 COVID RT-PCR positive cases and comparedwith 500 controls.Materials &Methods: Laboratory Based Observational study.Duration September 2020 to March 2021. RBC and platelet histogram, WBC scattergram graphic patterns along with platelet indiceswere noted in RT-PCR COVID-19 positive patients and comparedwith normal subjects utilizing automated haematology analyser XN11,500.Result: WBC scattergram and Histogram most of the COVID positivecases showed neutrophilia (96).Conclusions: Interpretation of the alteration in RBC and platelethistogram, WBC scattergram and Platelet indices in SARS-CoV-2infected patients can contribute timely clues for diagnosis and mayhelp in predicting the prognosis.
