England's Covid-19 smartphone app launched to curb the spread of the virus does not accept test results processed in the country's state-run laboratories, hospitals or as part of an official survey, it said on Saturday.
The App's official account said on Twitter it could not link to test results taken in Public Health England (PHE) laboratories, at the National Health Service (NHS) or as part of a survey run by the Office for National Statistics (ONS).
On Friday, 210,375 tests were taken, with 61,481 handled by PHE and the NHS, or 29 per cent. That does not include tests taken as part of the ONS surveys because they are counted on a UK basis.
Tests taken in hospitals includes patients and health care staff.
The NHS Covid-19 app was launched this week, four months later than expected. It uses Bluetooth signals to log when a user is in close contact with another user, generally meaning within two metres for 15 minutes or more.
If someone then tests positive for Covid-19, they can share the result anonymously with their close contacts, who will each receive an alert and will have to isolate for 14 days.
The launch comes as Britain braces for a second wave of infections, with daily cases numbers rising at rates not seen since the peak of the pandemic. Testing capacity has also increased.
The Department for Health did not give an immediate response but its website said it was working to rectify this issue as soon as possible.
