If you are over the age of 11 you are encouraged to take lateral flow tests twice a week (every 3 or 4 days) if you do not have COVID-19 symptoms.
You are also encouraged to take a test:
People who are unvaccinated contacts of positive cases and are self-isolating for 10 days should now take a lateral flow test on day two and day eight instead of a PCR test. This change is effective from 5 January 2022.
There is additional guidance for those working in health and social care and in educational provision.
If the LFD test result is negative, the individual does not need to isolate and is safe to attend work as long as they feel well and have no symptoms.
If the LFD test result is positive, you must self-isolate from the day of your test and for the next 7 days. You should take LFD tests on or after day 6 and 7 to check if you are still infectious before leaving self-isolation.
It is recommended that test results - negative or positive – are recorded on the UK Government portal Report a COVID-19 rapid lateral flow test result - GOV.UK (www.gov.uk).
Regardless of a previous negative LFD or PCR test, anyone who develops symptoms of the virus (a new persistent cough, high temperature or loss/change of taste or smell) or other cold or flu-like symptoms (headaches, tiredness general aches and pains), even if mild, should self-isolate and book a test as soon as possible through the online UK portal at www.gov.wales/coronavirus or by calling 119.
