Is this groundhog day?
'Experts' were wrong on rapid tests all along, first ignoring them, then rejecting them, and only accepting them with #omicron.
Now some reject throat swabbing because it is not how tests were approved by @GovCanHealth

Regulatory approval logic commands us to not use the BTNX test shown in the image 👆 because it is not approved for self-testing, nor for asymptomatic testing, as of today. 👇
Yet it is widely distributed and used for self-testing 🤔 2/n
A risk benefit-analysis strongly supports YES.
High risk of false negatives with nose swabbing, yet no reports of false positives owing to off-label throat swabbing.
