A number on countries and airlines now require passengers to prove evidence of a recent COVID-19 negative result prior to flying, with a certificate. At BHC we can provide COVID-19 RT- PCR tests via nasopharyngeal and throat swabs and results are given either within 24 or 48 hours. The test has a sensitivity of 98% and specificity of 100%. This test is very accurate at detecting SARS-CoV-2 and is currently accepted as border entry in all countries. Ideally the test should be taken three to five days before departure of the flight, but you should check the requirements of each individual airline. The test should be taken at the earliest time frame possible as results can get occasionally delayed and we cannot take responsibility for any travel disruption as a result of delayed results.

In addition we also provide lateral flow antigen test, which involves a nasopharyngeal swab, with same day results. Our test are on the approved government list and you can either come to our clinic to do the test or take it home and emails the results. 


All results will include a copy of the lab report and COVID 19 negative fit to fly certificate for international travel signed by our clinical team.

Please note:

Please bring your passport to the appointment as proof of ID and passport number. The timing of receiving your PCR results can vary between 24-48 hours depending on which time frame you choose. For the 24-48 hour results generally the majority of results come back within 48 hours however capacity at the lab and sample re-runs can mean the results may take slightly longer. We are not liable for any other costs should your results be delayed. Antigen tests results are all emailed by 6pm the same day. It is your responsibility to check if a antigen test or PCR test is required at your destination country.

If you choose the quantitative test it will also tell you the level of your antibodies after infection or vaccination.


If you have a negative result this could mean you have not had the infection, had a mild infection or your body had not produced antibodies at the time of testing.
