What is a ‘Fit to Fly - Lateral Flow’ Test

A ‘Fit to Fly Lateral Flow’ Test may also be referred to as an Outbound Antigen Test or a Rapid Antigen Test. This is a type of test to detect COVID-19 that can be taken at home. The service we offer enables you to present a ‘Fit to Fly’ certificate to your airline when you need to travel.

I no longer need my Fit to Fly test. Can I use it as a Day 2 test instead?

Please see our guidance on Day 2 Tests.

What is the difference between a lateral flow (Antigen) test and A PCR test?

PCR (polymerase chain reaction) tests have been designed to find genetic material called RNA that tells the virus to make these proteins. This test the most accurate Covid-19 test. When swabs are taken for PCR tests, reagents are used to convert the RNA into DNA in order to identify any infection within the patient. Antigen tests have been designed to find proteins on the surface of the virus to identify the pathogen. Antigen tests are often called rapid tests and are carried out by mixing the sample with a solution where it releases the viral proteins. The combination is normally applied on a paper strip that will be able to detect any antibodies that bind the protein.

How accurate are Lateral Flow Tests?

The test meets the requirements for the proof of a negative coronavirus (COVID-19) test:
The test meets performance standards of ≥97% specificity, ≥80% sensitivity at viral loads above 100,000 copies/ml.
