@Jetpixi It sucks that you're sick, & I hope you get better soon.
If your testing protocol doesn't already include it, coughing on the swab has been shown to increase accuracy.
The most effective current method is throat/mouth swab, then nasal swab, then cough 3 times with the swab as far back inside your mouth as possible without it touching anything.
The cough is the real game changer addition, as it tends to yield results more often than when just a nasal or a throat + nasal protocol is used.
