Is the Panbio COVID-19 test with Fit to Fly certificate accepted for KLM flights to the UK?

The CM Mediclinic provides a Panbio COVID-19 test that includes a Fit to Fly certificate, however, it is unclear if this test is acceptable for KLM flights to the UK. The KLM website lacks specific information on this test. Comments suggest checking government websites such as gov.uk for entry requirements, which state a negative PCR test is mandatory, along with self-isolation for a specific duration upon arrival. Additionally, quick tests like lamp and rapid antigen are acceptable as well, depending on the airport.
