Before a work meeting today I took today a home based lateral flow test using the new kits. In the past you had to swab your throat as well as one nostril. Now you only have to swab both nostrils and not your throat.
It was always pretty unpleasant for me to swab the back of your throat (it would usually make me "gag" a little) so I think that this new development will mean lots more people self testing.
Also, easier to use since the "extraction buffer tube" is now pre filled with the testing liquid and you only have to wait 15 minutes for the result.
