Antigen or PCR??
Hello, I am travelling to Spain September 28 th,after being there late July,so am familiar with the covid protocol, as in apps required to enter Spain, and UK ,locator form,etc,I am just holding on to book my "antigen 72 hours or less test "for return to uk wiith the same clinica I used last time,as when I look at the gov.uk website it says you are advised to take a pcr test,but how to interpret " advised"im not sure,it doesn't mean compulsory, or say that any of the other tests are sufficient ,if anyone flying to the UK around that time could tell me what they are doing it would be appreciated.
