There's evidence that for Covid-19 it's not necessary to go as far back as people have been going. There's also evidence that self-collection works well. The FDA has acknowledged this before and allowed self-collection with physician oversight before they allowed this test.
- MikeAmelung 6y agoWhere is this evidence? How does this square with the evidence that RT-PCR tests are already coming back falsely negative, probably due to missing the virus while swabbing? Pardon me for being skeptical, but this is all from the same people who have bungled this every step of the way.
- cbhl 6y agoI'm having trouble finding the actual study, but UnitedHealth Group, working with the Bill & Melinda Gates Foundation, Quest Diagnostics, and the University of Washington did a study on the efficacy of self-swabbing. https://techcrunch.com/2020/03/25/study-behind-updated-fda-guidance-shows-self-swab-tests-are-as-effective-as-those-done-by-clinicians/ https://techcrunch.com/2020/03/25/study-behind-updated-fda-g...
- James_Henry 6y agoI found the paper. I haven't read through it so I can't say if it is actually any good, but it is good enough that the FDA changed their recommendations because of it (that might not mean much, of course). https://www.medrxiv.org/content/10.1101/2020.04.01.20050005v1 https://www.medrxiv.org/content/10.1101/2020.04.01.20050005v...
- MikeAmelung 6y agoThanks for tracking it down. Doesn't seem to be any problem with accepting their results that it's almost as good as a nasopharyngeal swab, so you won't see me complaining about it again.
- takeda 6y agoNot really an evidence, but looks like their instructions explicitly say to not insert it deep: https://www.pixel.labcorp.com/covid-19-sample-collection https://www.pixel.labcorp.com/covid-19-sample-collection
