Objective:To identify helpful laboratory paprameters for the diagnosis and prognosis of COVID-19.Methods:An observational retrospective study was conducted to analyze the biological profile of COVID-19 patients hospitalized in the Unit of Pulmonology at Setif hospital between January and December 2021.Patients were divided into two groups:the infection group and the control group with patients admitted for other pathologies.The infected group was further divided according to the course of the disease into non-severe and severe subgroups.Clinical and laboratory parameters and outcomes of admitted patients were collected.Results:The infection group included 293 patients,of whom 237 were in the non-severe subgroup and 56 in the severe subgroup.The control group included 88 patients.The results showed higher white blood cells,neutrophils,blood glucose,urea,creatinine,transaminases,triglycerides,C-reactive protein,lactate dehydrogenase,and lower levels of lymphocyte,monocyte and platelet counts,serum sodium concentration,and albumin.According to ROC curves,urea,alanine aminotransferase,C-reactive protein,and albumin were effective diagnosis indices on admission while neutrophil,lymphocyte,monocyte,glycemia,aspartate aminotransferase,and lactate dehydrogenase were effective during follow-up.Conclusions:Some biological parameters such as neutrophil,lymphocyte,monocyte,glycemia,aspartate aminotransferase,and lactate dehydrogenase are useful for the diagnosis of COVID-19.
