Lateral flow tests are more accurate in tracing Covid than first thought according to a new study. The rapid tests, which provide users with a result in 30 minutes, have been previously criticised for being ‘inaccurate’.Comparisons are often made with PCR tests, which takes a much longer time for a result as they are sent off to a lab for a closer investigation.Lateral flow tests have become a key component in the fight against Covid - with Scots urged to test at home on two occasions every week.
Anyone who tests positive on a LFT must then book a PCR test, in accordance with current Scottish Government coronavirus rules.
