There’s the issue of false positives, false negatives and whether people who do test positive will self-isolate, said Paul Hunter, a professor in medicine at the University of East Anglia. “There will be some benefit there … but whether that benefit is sufficient is the question.” Added links to Ukrainian versions of 'Throat and nose test: COVID-19 rapid test kit instructions' and 'Nose-only test (SureScreen): COVID-19 rapid test kit instructions'.

The lateral flow devices that display the desirable performance characteristics are summarised in table 1 below. Table 1: summary of lateral flow devices that have passed phase 3a validation Lateral flow device Lateral flow tests (LFTs) – also called rapid tests – look for proteins on the surface of the virus that causes Covid-19, to ascertain the presence of the pathogen. They differ from gold-standard polymerase chain reaction (PCR) tests, which are engineered to find genetic material called RNA that instructs the virus to make these proteins. LFTs do not detect which variant of Covid-19 an infected person has.

The reliability of Innova tests also depends on who administers them. When they were initially piloted in Liverpool last year, scientists found that in a population of mostly people with symptoms, the test’s sensitivity fell to about 58% when administered by self-trained staff versus 79% when tested by laboratory scientists. In a study that looked at people without symptoms, sensitivity fell to roughly 49% versus PCR tests. How do experts weigh up the pros and cons? LFTs are more prone to false negatives than positives, so if you have suspicious symptoms and test negative, it's still worth erring on the side of caution.

There isn't any official government guidance about when to test anymore, so people are having to weigh up when is sensible to do so. Professor Adam Finn, a member of the UK’s Joint Committee on Vaccination and Immunisation (JCVI) told the British Medical Journal: “If [lateral flow tests] come up positive that means you are potentially infectious to others and must self-isolate. They are not ‘green light’ tests: you cannot be sure that if the test is negative you are not infectious, and you must continue to take the usual precautions.” When will lateral flow tests stop being free?

Testing advice in other parts of the UK

put the end of the swab into the tube so it's in the liquid and swirl the swab around as directed in the test kit instructions, then close the lid The advice is the same in Scotland, Wales and Northern Ireland, except the legal requirement to isolate remains. After a positive rapid test result, people should get a PCR test within two days at the latest, online or via 119, the Department of Health said. If the PCR test is negative, it will override the positive rapid result, and the person no longer has to self-isolate. If they don’t do a PCR test within that timeframe, they should self-isolate in line with the original rapid test result. Will rapid tests be used for so-called Covid passports, or certificates, in future?
