@mekkaokereke I hadn’t heard of the cough method before, but at some point I switched to these “alternative swabbing instructions”, based on reading about what was getting fewer false negatives as the new variations were gaining prevalence:
cough 3-5 times, then swab on the inside of both cheeks, above and below the tongue, on the gums and hard palate, for a minimum swabbing duration of 30 seconds
