Retesting for severe acute respiratory coronavirus virus 2 (SARS-CoV-2): Patterns of testing from a large US healthcare system	2020-08-10		.txt	text/plain	1056	61	52	Often decisions on who to test are left to individual clinicians, which leads to questions about when and who to retest for COVID-19, how often false positives or negatives might occur, and the duration of positivity. This report describes patterns of SARS-CoV-2 nucleic acid polymerase chain reaction (PCR) retesting in inpatients and outpatients within a large US healthcare system. We performed a retrospective chart review of all inpatients and outpatients aged ≥18 years receiving care within the University of Pittsburgh Medical Center (UPMC) with ≥2 SARS-CoV-2 PCR tests with an initial test between March 3 and May 3, 2020, and a subsequent test before May 21, 2020. In this retrospective study of a large US healthcare system, we found that retesting for SARS-CoV-2 was uncommon and often resulted in multiple negative tests.
