CONCLUSIONS: In a low prevalence area, repeat inpatient testing after an initial negative result, using a highly analytically sensitive SARS-CoV-2 RT-PCR, failed to demonstrate negative-to-positive conversion. In this paper we report the findings of a retrospective observational study to examine results of repeat SARS-CoV-2 RT-PCR testing for patients who were suspected of having COVID-19 (persons under investigation, or PUI) and asymptomatic patients and how the results may inform diagnostic stewardship within our academic medical center in Wisconsin. We believe the biggest lesson learned for our institution is that we found no cases of conversion from a negative to a positive result for inpatients undergoing a repeat PUI test or a repeat asymptomatic screen test. ./cache/cord-334210-lhadzo7o.txt ./txt/cord-334210-lhadzo7o.txt
