Description

For diagnosis of coronavirus disease 2019 (COVID-19), a SARS-CoV-2 virusspecific reverse transcriptase polymerase chain reaction (RT–PCR) test is routinely used. However, this test can take up to 2 d to complete, serial testing may be required to rule out the possibility of false negative results and there is currently a shortage of RT–PCR test kits, underscoring the urgent need for alternative methods for rapid and accurate diagnosis of patients with COVID-19. Chest computed tomography (CT) is a valuable component in the evaluation of patients with suspected SARS-CoV-2 infection. Nevertheless, CT alone may have limited negative predictive value for ruling out SARS-CoV-2 infection, as some patients may have normal radiological findings at early stages of the disease. Chest CT is a valuable component of evaluation and diagnosis in symptomatic patients. Chest CT findings are normal in some patients early in the disease course and therefore chest CT alone has limited negative predictive value to fully exclude infection. Chest CT is a valuable tool for the early diagnosis and triage of patients suspected. In an effort to control the spread of infection, physicians, epidemiologists, virologists, phylogeneticists and others are working with public health officials and policymakers to better understand the disease pathogenesis. For diagnosis of corona virus, RT-PCR, Antigen and CT scan test is routinely used. The system is developed the covid-19 testing and management analysis system. If the user wants to test the covid-19 disease, they can choose the test type and also book the time slot for testing the corona virus disease.
