I am writing a separate post as I thought the information my son-in-law sent was worth sharing. My daughter, her husband and my grandson had COVID last week (adults triple-vaccinated), all recovering well. Our family WhatsApp group has been busy as we are all desperately wanting to spend Christmas together so lateral flow tests are being used daily.
This London doctor talks about his experiences using LFTs. He has an open profile on Instagram so you can read his findings for yourself.
If you get a screenshot where you can't read all of the text, click on 'Expedition doctor' (his user name) and it will take you to his account.
In a nutshell it appears when doing an LFT test a throat swab is more accurate; anecdotal only but really interesting. So are the rest of his posts from the frontline in the fight against COVID.
