There has been a lot of confusion about the types of test for COVID-19 and when they should be used.

The Royal College of Pathologists has published a new, user-friendly guide to COVID-19 tests for patients and the public. People working in sectors such as social care, child care and teaching may also find it helpful.

The guide covers the most widely used diagnostic tests for COVID-19, PCR and lateral flow, exploring their accuracy and when they should be used.

It also provides an overview of antibody testing for COVID-19.
