How do I report a lateral flow test?

In England, Wales and Northern Ireland you should report your test result - whether it’s positive, negative, or void - every time you do Covid rapid lateral flow test at home or at work.

You need to report your result within 24 hours of getting it.

You can report your result on the UK government website, but you cannot report a result after more than 24 hours and you can only report one result at a time.

If you are taking daily rapid lateral flow tests because you are a contact of someone who has Covid, you should report your result every day.

If you cannot use the online service you can instead call 119 for free. Lines are open every day, 7am to 11pm.

Before you go to report your result, you will need:

To use this service, you need:

  • the QR code or ID number printed on the test strip (the part of the kit that shows your result)
  • a mobile phone number so you can receive a text confirming the service has your result

In Scotland, you should report your result through the NHS Scotland portal if you work in healthcare, social care and the NHS.

If you are visiting a care home you should also report your result through the NHS Scotland portal. You should then take a screenshot as proof of your negative test result.

If you don’t work in health or social care, you should report your result on the UK government website.

However, if you continue to test positive you must remain in quarantine for the full ten-day period.

If you are asymptomatic and get a positive lateral flow test result, you do not need to confirm the result with a PCR test. You only need to confirm a positive lateral flow test if:

  • you’re eligible for new Covid-19 treatments
  • you’re asked to do so as part of research
  • you have a positive rapid lateral flow test on or before day 2 of arriving in England from outside the UK

However, if you are experiencing symptoms of Covid-19, then you should order a PCR test.
