People may wish to use Covid tests less regularly after they are charged in England and Scotland from 1 April. When is the optimal time to use one?
For months many of us have used a single red line in a plastic cartridge as a kind of social traffic light – swaying whether go out or stay at home to protect others from Covid. But from 1 April, lateral flow tests (LFTs) will cease to be free of charge in England and Scotland, meaning people will want to use them as economically as possible (if they bother testing at all). Wales are implementing a phased approach to charging for tests from the same date.
So, when is the optimal time to test if LFTs are limited and you want the greatest chance of knowing if you’re infected?
