On Lateral Flow Test?

Rapid lateral flow tests are for people who do not have symptoms of coronavirus (COVID-19). The tests give a quick result using a device similar to a pregnancy test. If you have symptoms of COVID-19, you'll need to do a PCR test. There's separate information on how to do a PCR test.

What are the chances of a false positive COVID-19 lateral flow test?

This is because the specificity of LFTs – their ability to accurately diagnose uninfected individuals – is higher, and therefore false positives are highly unlikely. In people who did not have COVID‐19, LFTs correctly ruled in infection in 99.5% of people with COVID-like symptoms, and 98.9% of those without them.

Can COVID-19 antigen tests be false positive?

Despite the high specificity of antigen tests, false positive results will occur, especially when used in communities where the prevalence of infection is low – a circumstance that is true for all in vitro diagnostic tests.
