Growing evidence supports a causal relationship between SARS-CoV-2 and cutaneous manifestations 1 . 2 However, interpretation of SARS-CoV-2 PCR/antibody results in dermatology patients with probable COVID-19 infection remains difficult due to lack of data to inform optimal test timing.

Our international registry for cutaneous manifestations of COVID-19 1, 3 asked providers to report time between dermatologic symptom onset and positive/negative COVID-19 laboratory results. nasopharyngeal swab PCR are influenced by kinetics of nasopharyngeal shedding, which are difficult to assess in non-respiratory presentations.
