• Adamson et al. conducted a retrospective analysis of 10,165 SARS-CoV-2 test results from the UCLA Health System to determine the diagnostic yield of repeat testing and found that among 808 patients who did repeat testing following an initial negative test, only 2% subsequently tested positive. Investigators suggest certain clinical scenarios may benefit from repeat testing, such as in healthcare workers with ongoing exposures or hospitalized patients with high suspicion.
