This 60-years old man came for a CT KUB, which shows a right ureteric calculus.
The lower lobe lung images that are always captured on a CT scan of the abdomen show changes of COVID-19, for which the patient is and was asymptomatic. Are these new or old or resolving or active? I guess an antibody test would tell us whether the patient has been infected in the recent past and an RT-PCR test would tell us whether the patient is current infected or not.
However we have no idea how many patients actually get further tested further.
