Just looking at entry requirements for France for school trip for DD in the summer. It says 'negative PCR or antigen test result taken 24 hours pre-departure'. I know I should know this by now, but is an antigen test the same thing as the lateral flow tests we've all been doing at home?
And if so, how can countries trust the results when they can so easily be faked? I've always assumed it would need to be a test administered by a healthcare professional so the results are more robust?
