![]() It is important, however, that the tests are carried out correctly by qualified personnel, as was the case in our study.' 'The study supports efforts to conduct population-wide LFT tests. In the context of future relaxations of lockdown rules - in addition to vaccinations - the early detection of people with infection through reliable tests will be necessary in order to control COVID-19.'ĭr Oliver Lammel, clinical lead of the study, said: 'The study results provide the basis for future containment strategies in primary care, which can make an important contribution in control and prevention of a pandemic. 'Our study is the first study to demonstrate that point-of-care antigen testing using lateral flow tests combined with clinical assessment of symptomatic patients can rapidly and accurately detect SARS-CoV-2 infection in primary care.'ĭr Thomas Czypionka from the Institute for Advanced Studies, Vienna, said: This highlights the necessity of testing at early infection with lateral flow tests, and shows that in patients who are newly symptomatic, the two testing methods have similar levels of accuracy. 'In our study, both shorter duration of symptoms and higher viral load were significantly associated with a positive lateral flow tests. Our findings support this move, but ensuring tests are properly administered should be integral to any strategy.'ĭr Jasmina Panovska-Griffiths from the Big Data Institute and The Queen’s College at University of Oxford added: 'Countries are considering using lateral flow tests to manage future waves of the pandemic. But we have found that in patients who are newly symptomatic, the two testing methods have similar levels of accuracy. 'Previous studies have suggested lateral flow tests may be less sensitive than PCR in detecting Covid-19, particularly among asymptomatic individuals and during the early or late stage of an infection when the viral load is lowest. Study author Dr Werner Leber from Queen Mary University of London said: ![]() It also included the variables of a real-world setting: five different brands of test kit, three laboratories, and professional swabbing offered at 20 GP practices. The study is the first to compare lateral flow and PCR testing on the same group of people on a large scale. The lateral flow tests detected more than 95 per cent of the cases found by PCR, and correctly identified 89 per cent of cases as negative. Those who were suspected to have Covid-19 were also tested using a PCR test. The finding could be pivotal to national strategies looking to tackle the next phase of the pandemic, especially as timely and rapid testing becomes even more important once the current restrictions lift in England.Īs part of the study, over 2,500 people with mild to moderate flu-like symptoms were assessed by GPs in the district of Liezen (population 79,652), Austria, between October 22 and Novemand tested for viral antigen using lateral flow tests. Lateral flow tests are cheaper and produce a result in just 30 minutes - much faster than the time it takes to receive a PCR test result, which can take 1-3 days. ![]() A new study by researchers at the University of Oxford, Queen Mary University of London, Institute for Advanced Studies, Vienna, and the Medical University of Graz, has found that lateral flow tests detect Covid-19 with similar accuracy to laboratory-based PCR tests, providing they are used at the onset of infection and soon after symptoms start. ![]()
