- [pre-print, not peer-reviewed] Among 15,920 individuals presenting to Michigan Medicine for COVID-19 testing between March 10 and June 4, 2020, most (85%) only tested once and never tested positive (93%). A subset of 15% underwent multiple tests (average 2.6 tests per person). Non-Hispanic Black people were more likely to have additional testing than non-Hispanic white people (OR=1.21). Women were less likely than men to have additional testing (OR=0.86). Among 1,167 patients with at least one positive result, hospitalization (aOR=7.44) and ICU-level care (aOR=6.97) were significantly associated with repeated testing.
