THE SIGNIFICANCE OF COMPLETE BLOOD BLOOD COUNT AS LABORATORY DIAGNOSIS IN COVID-19

The increased global prevalence of COVID-19 has resulted in a significant increase in the occupancy rate of healthcare facilities, resulting in overcrowding in some areas. In this situation, healthcare staff must efficiently assess patients' status and undertake risk stratification, particularly in a triage setting. The complete blood count is a easily available, cost-effective, and time-saving testing procedure that may be useful in supporting those processes. This review examines changes in complete blood count parameters in COVID-19 patients with the goal to identify the most common changes in the parameters and their relationship to illness progression and severity. Anemia, increased red blood cell distribution width, decreased white blood cell count, significant alterations in white blood cell differential count, and thrombocytopenia were all prevalent symptoms in COVID-19 patients. Changes in complete blood count values and their magnitude are thought to provide useful information regarding illness severity and prognosis. Finally, COVID-19 patients have a consistent pattern of abnormalities in complete blood count values that arelinked to illness development, severity, and prognosis. Given the useful information offered by the test, it is envisaged that complete blood count evaluation would play a significant role in COVID-19 management
