Vox (Aug. 27) – Rebecca Lee Smith, an epidemiologist at the University of Illinois, said that at-home testing could theoretically lead people to get someone else to take the test for them. That was a point of discussion at her university, where they eventually opted for supervised (rather than collected-at-home) saliva-based PCR testing. “We decided that it was more important that we know, for sure, that the person who checked in for testing is the person giving the sample,” she says.
