Background & Objective: Coronavirus is an enveloped RNA virus that mainly causes respiratory infection. Real-time reverse transcriptase polymerase chain reaction (RT-PCR) test of nasopharyngeal and oropharyngeal swab is the confirmatory diagnostic test for severe acute respiratory syndrome coronavirus ۲ (SARS-COV-۲) infection. The relationship between SARS-COV-۲ and body fluid parameters is still not known. There have been few studies regarding the correlation between urine biochemical parameters and SARS-COV-۲ infection. The aim of the study is to determine the importance of urinary biochemical parameters in SARS-COV-۲ infection and whether these parameters can be used to predict the severity of the infection.Methods: This was a retrospective observational study consisting of total of ۲۸۵ patients diagnosed with SARS-COV-۲ infection. The patients were divided into three groups according to the severity of infection as mild (۱۲۰ cases), moderate (۱۱۰ cases) and severe (۵۵ cases). During the study period ۷۲ healthy persons were enrolled as controls. Analysis was done to find any relationship between various urine biochemical parameters and the severity of SARS-COV-۲ infection.Results: Urinary occult blood (U. Blood) and Urinary protein (U. Pro) have higher positive rates in SARS-COV-۲ patients as compared with healthy controls. Among the severities of SARS-COV-۲ infection (mild, moderate and severe), both these parameters were significantly higher. Glucose (Glu) and Ketone (Ket) positivity rate was more in moderate cases of SARS-COV-۲ than mild cases.Conclusion: Urinary biochemical parameters are very useful in identification of SARS-COV-۲ infection and also have the advantage in evaluating the progression in patients infected with SARS-COV-۲. Among the different parameters, Urinary Occult Blood and Urinary protein are significant in the differentiation of SARS-COV-۲ severity.
