A negative result means it’s likely you are not infectious.
But a negative test is not a guarantee you do not have COVID-19 and there’s still a chance you may be infectious. You should follow advice on how to avoid catching and spreading the virus.
If you did a rapid lateral flow test at home, report your rapid lateral flow test result as soon as possible.
When to self-isolate
You may need to self-isolate if you're told to by NHS Test and Trace even if you have had a negative test result.
You may also need to self-isolate if someone you live with has tested positive. Check if you need to self-isolate
You may still need to quarantine after a negative test if you've recently travelled to England from abroad. Find out how to quarantine when you arrive in England on GOV.UK
If you feel unwell
If you still feel unwell after a negative test, stay at home until you're feeling better. Contact a GP if your symptoms get worse or do not go away.
Check with your employer before going back to work.
If you're being sick, have diarrhoea or have a high temperature, stay at home until 48 hours after they've stopped.
If you get COVID-19 symptoms after the test, you need to get tested again.
