Introduction: Introduction: COVID-۱۹ has been a global pandemic since the end of ۲۰۱۹, and it is important to determine the complications and mortality of patients according to their paraclinics. Due to the numerous statistical gaps between different studies, in this study, the consequences of COVID-۱۹ were examined according to paraclinical cases in inpatients admitted to Valiasr Hospital in Qaemshahr in ۲۰۱۹-۲۰۲۰. Material and Methods: This research is in the form of a descriptive-cross-sectional. Blood tests at the time of admission of definite patients with COVID-۱۹ were the basis of the study of patients in the ordinary and special care departments of Valiasr Hospital, Qaemshahr. After obtaining permissions and determining the entry and exit criteria of patients' files, the researcher made a checklist based on the goals of the study variables provided, the information was completed and analyzed by SPSS version ۲۶. Results: Generally, ۶۷. ۱% of patients were hospitalized in ordinary wards and the rest were hospitalized in special care wards. ۵۳.۳% of all patients were men. The age group of ۷۱-۸۰ years had the highest frequency. ۱۰۰% of patients had lung involvement in chest imaging. The results showed that ۴۷% of patients had leukopenia and ۳۴.۶% of patients had lymphopenia. The results for PMN showed that only ۱.۳% of patients had neutropenia, while ۱۲.۹% of them were in the normal range. Thrombocytopenia disorder was observed in ۶.۹% of patients. Conclusion: Male sex and old age had the most cases of disease and mortality. An increase in the level of CRP, liver enzymes, neutrophilia, leukopenia, lymphopenia, leukocytosis, and thrombocytopenia was among the most important and common paraclinical consequences of COVID-۱۹. Neutropenia, thrombocytosis, and lymphocytosis were not associated with mortality, which requires further studies.
