Routine laboratory tests are essential for identifying COVID-19 cases. Reviewing the clinical features of confirmed COVID-19 cases retrospectively can offer valuable insights, the data were collected from 240 files, which included all files from the beginning of the opening of the isolation center in first of June 2020, until the 30th  of December 2021. Of the 240 cases, 100 cases were dead. Of survived cases, 54% were male and 46% were female. While the dead cases, 56% were male and 44% were female. In conclusion, the blood cell count plays a crucial role in both diagnosing and predicting the outcome of COVID-19, serving as a routine diagnostic tool. Low levels of leukocytes and differential white blood cell count can serve as indicators of a COVID-19 infection, while higher counts may indicate the progression of the disease. Conversely, lymphocyte and D-dimer levels do not provide diagnostic value but are indicative of the severity of COVID-19 cases.
