Are the tests suitable for travel?
As part of our PCR testing service, we will provide you with a testing certificate which is sufficient documentation for travelling in most cases. This is outlined by the travel guidance provided by the Foreign office Travel requirements in the current climate are ever changing so please do confirm what is required for your travel in advance with either your airline or the Embassy for your travel destination.

It is your responsibility to understand your specific requirements and ensure that our service is suitable for you. We cannot advise on what is required for any particular journeys.

Which test do I need?
Your travel destination may require a specific method and equally, may not accept home-testing. In the current climate, travel requirements are ever-changing – please confirm what you need with your airline and/or the embassy for your travel destination before you purchase one of our tests.
When should I take my test?
Each travel destination and airline have their own specific requirements. Please check when your required timeframe starts and ends with your airline and/or the embassy for your travel destination before booking. It is your responsibility when booking for travel purposes to choose a suitable appointment or test date in correspondence with their specific requirements.

We always advise that you take your test as early as possible within your required timeframe.

How do I post my test?
Royal Mail Priority Post Box – you will receive a postage label in your kit. Where possible, please post prior to 12pm (or the latest pickup time for your local priority post box) to ensure it arrives at the lab within 24 hours. We will not be liable for any outcomes as result of postage delays.
We always advise that you take your test as early as possible within your required timeframe.
Is there any preparation required before taking my home swab test?
Do not smoke, drink, eat, chew gum, or brush your teeth for the 30 minutes before taking your test to avoid contamination of your sample. Non-compliance with this advice can render your test result inconclusive.
Do you test patients with symptoms?

No, please follow current government guidance.

What does an unclear or inconclusive result mean?

A small number of tests may come back unclear or inconclusive. This simply means it was not possible to say if you had the virus when the test was done. There are a number of reasons why this might happen, and it unfortunately means you will need to be tested again. If this happens, we may offer you a new test kit at no extra cost. Please see our Terms of Service

What happens if I test positive?

Please follow current government guidance at:

As Covid-19 is a notifiable disease we are required by law to report all cases of Covid-19 to Public Health England.

Yes – please see our Refund Policy in our Terms of Service You are not required to send the unused kit back to us, please dispose of it safely.

Once the refund has been requested, it can take up to 14 days for the refund to be processed.

My flight was cancelled / changed. Is my test still valid?
If your flight has been changed or cancelled and your testing period now falls outside of your stipulated timeframe, your results will now be invalid unless advised otherwise by your airline or the embassy for your travel destination.

What are antigen tests?

Antigen tests detect viral RNA. Usually, this requires taking a swab from the nose and throat and then analysing the specimen in the lab using the polymerase chain reaction (PCR). You may see these tests referred to as PCR tests. They aim to answer the question: do I carry coronavirus now?

What does “test accuracy” actually mean?

Test accuracy refers to two separate concepts: sensitivity and specificity.

Sensitivity concerns the false negative rate and is expressed as a percentage: out of 100 truly positive patients, how many are detected as positive by the test? The higher the sensitivity, the fewer the numbers of false negatives.

Specificity concerns the false positive rate and is expressed as a percentage: out of 100 truly negative patients, how many are detected as negative by the test? The higher the specificity, the fewer the numbers of false positives.

Why take a PCR antigen test?

An antigen test detects the presence of viral RNA. It aims to see if the virus is detectable now. 

The test is taken to:

Diagnose CURRENT infection

Test following infection to see if the virus has been cleared.

Screen asymptomatic individuals to detect if they carry the virus and are potentially infectious

Antigen tests are a crucial part of mitigating transmission as we come out of lockdown. We need the ability to detect the carriage of Covid-19 and respond to it rapidly. As people return to work, and society tentatively re-opens, robust testing programmes as part of a return-to-work strategy will be key to reduce spread and improve confidence amongst employees and customers. 

What does a positive antigen test result mean?

A positive PCR antigen test means that the Covid-19 virus has been detected on the swab. These tests are highly specific (the specificity is 100%). This means that the false positive rate is negligible. If the result is positive, it is highly likely to be true. 

The test detects viral RNA and does not tell the difference between active viral infection and “dead” viral remnants. It therefore cannot distinguish between someone who is infectious (active virus) and someone who is not (virus shedding). To do this, you would need to extract the virus particles and try to infect cells to see if this is possible. 

What does a negative PCR antigen test result mean?

A negative result could mean one of several different things:

A genuine negative test result: the person does not carry Covid-19. They may never have had it, or they have had it and cleared the virus to levels low enough that it is no longer detected. 

A false negative result: the sensitivity of the test is around 99%. The technique used for the swab is important, so please follow the instructions carefully.
