The Correlations Between Epidemiological and Clinical Characteristics, laboratory tests and CT Scan reports in the diagnosis of cases ۲۰۱۹ novel coronavirus pneumonia. A Diagnostic Accuracy Study

Background and Aim : The role of laboratory parameters and the relationship of them with radiology reports, CT scan and clinical outcomes in screening of COVID-۱۹ patients not been definitely established, but this disease presented a major challenge in the field of clinical tests, radiology reports, clinical outcomes that help to monitoring and treatment COVID-۱۹ disease. Methods : This study was performed on ۳۴۰ suspected COVID-۱۹ patients, who presented to Chamran Hospital, Shiraz University of Medical Sciences Shiraz, Iran from ۲۰ February to ۳۱ August, ۲۰۲۰. Information each patient's will be completed using a data collection forms based on records. The evaluation of lungs involvement in CT scan and their relationship with laboratory indicator including biochemical and hematological factors, is the best scale for the severity and prognosis of Covid ۱۹ patients. Results : The findings of this study indicated ALT, AST, CRP, NEU, LDH, and Urea have very good accuracy in predicting cases with positive RT-PCR for COVID-۱۹. Considering the significant difference in CT scoring and laboratory parameters, can hope to model or predict the results of coronavirus testing based on routine laboratory tests. We realized CT scan findings may be predictive of patients ‘outcome and had a correct correlate with laboratory findings and disease severity.Conclusion : In conclusion, finding of this study shown the correlation of clinical and laboratory findings with CT-based quantitative score of pulmonary involvement in COVID-۱۹ pneumonia and our findings could be usable to development future clinical research associated with COVID-۱۹ infection and show relationship of CT scan reports and clinical outcomes in the diagnosis and severity of patients with COVID-۱۹.Thus, expected future studies can indicated better clarify impact on clinical decision-making and larger clinical trials.
