Fundamentals of using a Combined Diagnostic Approach for Covid 19 By RT-PCR and HR-CT Scan for early Case Recognition

Abstract

The emergence of more and more variants of COVID 19 and not ending pandemic is still a top most concerns around the Globe. The diagnosis of COVID19 is still a bit challenging. The asymptomatic phase during incubation period of disease or prodromal symptoms, mislead the clinician to early diagnose a case. Therefore this short communication was aimed to highlight a combined diagnostic approach for COVID by using HRCT scan chest and RT – PCR. This will be helpful for the clinician to early diagnose and timely manage a case, ultimately a step forward to contain this disease and its mortality. This commentary concluded that the sensitivity along with specificity of HR-CT scan and PCR varies. This variation could be due to many factors like mode of analysis, machines used for HR-CT scan or RT-PCR, technical handling. Therefore, though it become costly but a combined diagnostic approach should be used to early diagnose and manage COVID.
