At the moment, only patients in hospital with flu-like symptoms are being routinely tested for the virus.
However, there have been calls to do more tests, especially for NHS staff and other key workers
…
The test being used is known as a PCR test. A swab from your throat or nose has to be taken and tested in the lab.But scientists are also looking at tests which can check whether someone has had the disease in the past. These look for markers of immunity called antibodies in the blood.
They are faster than PCR tests, using a drop of blood on a device a bit like a pregnancy test.
This could help work out how widespread the disease has been and whether people are safe to go back to work
