An Australian surgeon has demonstrated the correct way to do a rapid antigen test and the common mistake many people are making - putting swabs too far up the nose.   

Dr Eric Levi, an ear, nose and throat specialist from Melbourne, has posted a series of helpful video to his TikTok account which show parents the right and wrong way to perform the tests - which contain lessons for us all. 

Dr Levi said people have come to believe they need to insert the swab really deep because of PCR tests performed upon them, but that is not necessary with RATs.

'The aim is to go low and slow - aim for the back of the nose,' he says.
