High-Resolution Computed Tomography (HRCT) tests
The chest scans are being increasingly ordered for patients at risk- those who are showing classic signs of the infection but get a negative COVID RT-PCR report (either due to faulty testing or premature incubation period).While the usual PCR tests- RAT (Rapid Antigen Tests) and RT-PCR (Real-Time Polymerase Chain Reaction Tests) find out the viral presence by collecting samples from the nose and/or the throat, an HRCT test is a diagnostic tool that involves imaging of the lungs.

CORADS, which stands for COVID-19 Reporting and Data System determines the level of infection and involvement because of the virus. CORAD scoring is done on the basis of 1-6, wherein 1 signifies a ‘negative COVID’ or normal lung function, scores 2-4 signify suspected viral involvement and a reading of 5 means classic COVID-19. A person who has detectable ground opacities in the lungs is given a score of 6 and said to be at a higher risk of COVID severity.
CT Score –Different labs go by different readings, with most scores being considered between 1-40 or 1-25. A higher score usually represents greater lung involvement and high COVID severity.
