Lateral flow testing involves a swab of the nose and throat to collect a sample and provides a result within around half an hour. The sample runs along the surface of the pad, showing a visual positive or negative result dependant on the presence of the virus. The number of false negatives can increase significantly simply due to the lack of understanding people will have in testing themselves.
Regarding lateral flow tests generally, adam finn, professor of paediatrics at the university of bristol, explains: The lateral flow device (lfd) kits can be picked up from testing sites, pharmacies or sent through the post. These are 'red light' tests. Prof deeks and other academics are concerned that people will get a negative test, think that means they definitely do not have coronavirus and do things they should not.

Lateral flow assays, often known as rapid test devices or rdt's are immunosensors that rely on the use of low cost materials to achieve the flow of reactants. With a lateral flow test, a liquid sample is placed on a small absorbent pad.
Lateral flow tests can return results significantly faster than the pcr because the swab does not need to be sent to a laboratory but can instead by this means about 23% of people who actually do have covid will be returned as negative when using a lateral flow test.
