Coronavirus (COVID-19) test sample could not be read (void)

If your test sample could not be read or you got a void result, it's not possible to say if you had coronavirus (COVID-19) when the test was done.

To check if you have COVID-19, do another test as soon as possible.

If you did a PCR test from the NHS (a test that is sent to a lab), call 119 (free from mobiles and landlines) to order a test.

If you did a rapid lateral flow test from the NHS (a test that shows you the result on a device that comes with the test), find out how to order free NHS rapid lateral flow tests on GOV.UK.

If you're going into hospital for a procedure

If you did the test because you're going into hospital for a procedure, contact the hospital as soon as possible to find out what to do.

If you have symptoms of COVID-19
