COVID-19 rapid lateral flow tests show the result on the testing device.
What your COVID-19 test results means
Positive test result
If you get a positive result, it means it’s very likely you have COVID-19.
Try to stay home and avoid contact with other people for:
- 3 days if you are under 18 years
- 5 days if you are 18 or over
If you're eligible for COVID-19 treatments and you get a positive result, you must report your result so the NHS can contact you about treatment.
Negative test result
If you get a negative result, it means it's unlikely you have COVID-19.
There's still a chance you could have the virus, so you should follow the advice on how to avoid catching and spreading COVID-19.
If you’re eligible for COVID-19 treatments and you get a negative result, you must report your result as you may need to do another test.
Test result could not be read
If your test result could not be read (some tests may call this a void result), it’s not possible to say if you had COVID-19 when the test was done.
Do another test as soon as possible.
If you’re eligible for COVID-19 treatments and you get a void result, you must report your result.
