Background: Every day, more and more countries throughout the world reported a rise in the prevalence of COVID-19 infections. Finding clinical and laboratory indicators of worsening disease severity and mortality is of the utmost importance as this epidemic continues to spread. Recovery from a COVID-19 infection does not eliminate the effects on many hematological and immunological laboratory parameters. In this study we aimed to assess Hematological and Immunological Laboratory findings among COVID 19 patients and if there is possible relationship between these parameters with Covid-19 disease severity.

Conclusions: In the absence of evidence from a real-time polymerase chain reaction or antibodies, a thorough familiarity with the laboratory findings and hematological abnormalities linked to SARS-CoV-2 infection might aid in raising suspicion of illness. Rapid screening, diagnosis, prognosis, and treatment of COVID-19 patients could be aided by blood counts in addition to morphological alterations in peripheral blood. Both the diagnosis and the prognosis depend on the thrombocytopenia count. Infection with COVID-19 is indicated by low leukocyte and neutrophil counts, but the opposite is true for progressive infection: increased levels.
