This depends on what test types your destination accepts. Some countries only accept NAAT tests (e.g. PCR, TMA or LAMP), while others accept antigen lateral flow test results if an approved provider has verified them (e.g. they have produced a test result certificate for you).
Tests from an approved provider or laboratory should contain your name and the date of your positive Covid-19 test (within the last 7-180 days). These can be a PDF or a screenshot/photo of a UK NHS test result provided your name, and the date are visible.
Please note: We cannot accept screenshots/photos of positive Covid-19 test results from other national health providers. We can only accept PDFs from a laboratory with your full name and the date of your positive Covid-19 test result clearly displayed.
We also cannot accept evidence of vaccination as proof that you have recovered from coronavirus.
