Is there such a thing? I have just ordered a box from the NHS as per usual, but I have reason to think they are not very accurate. DS appears to have Covid for the second time in 4 months ( so much for immunity) but his LFTs were negative last time and are negative this time. Waiting for PCR. He has very mild symptoms. Almost asymptomatic.
I thought I saw some posts talking about more accurate LFTs.
