To make an appointment for a coronavirus test, residents should call 119, or book via the government website.
Peterborough City Council has advised on social media that if appointments aren't immediately available, people should try again in a few hours. New appointments go live throughout the day. Self-isolating needs to continue while waiting for a test.
Tests should only be booked for those who are experiencing symptoms of coronavirus - a fever, a new and continuous cough or a loss or change in sense of taste or smell. People who are not exhibiting these symptoms and have no cause to suspect they have been in a situation that has increased risk of infection are asked not to book a test.
Speaking on BBC Radio 4's Today programme, the professor overseeing the government's antibody test programme, Sir John Bell, said that the surge in demand for tests is down to a second wave. He said: "A month ago they had spare capacity in testing – significant spare capacity – but I think what has been underestimated was the speed at which the second wave would arrive, but also the pressure put on the system from children returning to school, and the testing demands associated with that, and people increasingly out and about."
He said that there would be a "significant increase" in testing capacity over the next fortnight, but warned that the winter could "add additional confusion" due to the expected rise in colds and other illnesses with similar symptoms.
