Abstract
The outbreak of a corona virus novel causing corona virus disease in2019 (COVID-19) was officially declared as a pandemic by the WHO in March 2020. With over 80 million cases has been documented tilDecember 2020, COVID-19 is a significant cause of morbidity and
mortality all over the world. Laboratory diagnosis of COVID-19 infectionis through real-time polymerase chain reaction (RT-PCR) which isconsidered the gold standard diagnostic method in multiple studies. (231,232)The clinical manifestations of COVID-19 infection are diverse,ranging from asymptomatic to life threatening pneumonia. (233) Earlydiagnosis and risk stratification of patients with COVID-19 issignificantly essential to facilitate patient isolation protocols and
management.(234)Now, a variety of hematological manifestations of SARS-CoV- 2ranging from cytopenias to coagulopathy are also being discovered,which can be also used for predicting the prognosis in patients withCOVID-19 infection. (237)As the pandemic continues to spread, it has become increasinglyimportant to identify reliable predictors of mortality and ICU admissionamong COVID-19 patients. Laboratory markers, such as CBCparameters, CRP, D-Dimer, IL-6, and serum ferritin, have been proposedas potential predictors of mortality and ICU admission in COVID-19patients.95Our study aim was to develop and validate a clinically relevant riskstratification aiming to the furtherance of COVID-19 patients’ plan ofmanagement throughout evaluating and improving the efficacy of the>hematological biomarkers’ predictive value for the COVID-19 patientneed to ICU admission and their mortality rate.<This was an observational cross-sectional study, carried out in
