What is the REACT study?

REACT (REal-time Assessment of Community Transmission) is a series studies that are using home testing to improve our understanding of how the COVID-19 pandemic is progressing across England. This major research programme was commissioned by the Department of Health and Social Care (DHSC) and is being carried out by Imperial College London in partnership with Ipsos MORI and Imperial College Healthcare NHS Trust. Here’s our announcement from when the study first launched in April 2020.

REACT takes two main approaches to track the virus in the population, looking for both current and past infection.

Find out how REACT is assessing different antibody tests for accuracy and ease of use at home

Professor Helen Ward, Professor of Public Health at Imperial College London, talks about her involvement in the REACT study to assess a range of different antibody tests for their accuracy against SARS-CoV-2 (the virus that causes COVID-19) and how easily people can use them at home.

Steps involved in developing and assessing antibody test

Developing effective antibody tests for COVID-19

Prof Graham Taylor walks through what's involved in developing and assessing antibody tests

Professor Graham Taylor, Professor of Human Retrovirology in the Department of Infectious Diseases at Imperial College London, is part of a team carrying out antibody testing to assess if a person has previously been infected with the coronavirus that causes COVID-19. At the Imperial College Academic Health Science Centre (AHSC) COVID-19 webinar series, he talked us through how teams at St Mary’s Hospital and North West London Pathology based at Charing Cross Hospital, part of Imperial College Healthcare NHS Trust, were performing developing and testing antibody tests to inform a nationwide study.

Q&A with the REACT team

REACT researchers Dr Atchison and Prof Barclay host a public Q&A session on antibody testing

Dr Christina Atchison and Professor Wendy Barclay gave a live Q&A session on 22 July to share all things testing, from why antibody testing is helping our response to the outbreak, to why it's too soon to rely on them to change our behaviour. They responded to questions posed by a live online audience.

Scientists explain antibody testing work to track the spread of COVID-19 in the UK

Researchers at Imperial College London have been working with clinicians at Imperial College Healthcare NHS Trust on a programme of work to develop a ‘gold standard’ antibody test that can be used widely to track rates of coronavirus infections in the UK’s population.
