After the 2020 pandemic, a number of countries and airlines require passengers to prove evidence of a recent COVID-19 negative result prior to flying, with a certificate. At Best Health Clinics 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 provide the lateral flow antigen test, which involves a nasopharyngeal swab, with same day results. Our test is on the approved government list and you can either come to our clinic to do the test or take it home and email us 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:

Remember to 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 an antigen test or PCR test is required at your destination country.

Antibody test

Qualitative or quantitative COVID-19 antibody tests, to detect if you have had an infection in the past, or if you have produced antibodies in response to the COVID-19 vaccine.



Antibody test

Qualitative IgG/M:

This test tells you if antibodies have been detected and if you have been infected in the past. 

  • Home kit via finger prick      £65

  • In clinic via blood test          £100

Quantitative IgG/M:

This tests tells you if antibodies have been detected after an infection or COVID vaccination and gives a value to your antibody response.

  • Home kit via finger prick      £85

  • In clinic via blood test          £120

The antibody test should be performed 14 days or more following exposure or onset of symptoms or vaccination. You must ensure all your symptoms have cleared up before you book the test.


With the home test, a pack can be collected from the clinic or it can be posted. Full instructions are included for you to be able to take a sample via a finger prick, and a pre-paid envelope is supplied for you to post the sample to the lab, or you can return it to the clinic for our couriers to collect. 


The blood test undertaken at our clinic and a sample are sent to the lab in London.


The results are available in one to two days time (please note: if you are posting the sample the turnaround time will be delayed by another day). The test is approved by Public Health England and is very accurate.


What does the COVID-19 antibody result mean?

A positive result means you have had COVID-19 in the past, although we cannot tell when. As this is a new virus it is not known if a positive result means you have immunity and you will be protected fully or partially from future infection, or how long the immunity will last. 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.


Who can have this test?

This test is suitable for anyone who wants to find out if they could have been infected with the virus, either because they had symptoms or they are worried they may have had an asymptomatic infection. It can be used post COVID vaccination to see if you have produced a good antibody response to the vaccine. It can also be used by employers looking to bring their staff back to work and they want to see who has had COVID-19 already.
