Because of the variety of destinations our customers are travelling to, and because of the varied rules and restrictions in place in each destination, we are unable to advise on which test you should take or when you should take it. If you have queries, please bring these to a healthcare-professional led appointment and speak to your clinician.
As we are providing COVID testing services to patients travelling to 50+ destinations we are not able to advise about when travellers should take a test as each country's testing requirements differ substantially and are constantly changing. We recommend reviewing the Government website for your destination to understand their specific requirements. We do encourage travellers to book as early as they can within their travel window.
Our service uses a RT-PCR method to detect the RNA (ribonucleic acid) contained within the SARS-CoV-2 virus.
Please check the instructions provided in your test kit for return guidance.
The results timeline for our standard tests are provided on this page, for the expedited service on this page. For Hong Kong ISO15189 testing, please allow an additional 12-24 hours and request ISO15189 testing. All timelines are indicative timelines. Due to the changing nature of the pandemic, it is not possible to guarantee lab turnaround times. We cannot be held liable for costs incurred due to delayed results. You will be asked to sign a waiver prior to your test accepting this.

Your booking reference number is the number you are required to enter on your passenger locator form before travelling to the UK. It is displayed on your PDF receipt sent at the time of booking. The reference number is MAYFI, followed by the number 0 and your 6 digit invoice number.
You can collect your sample anytime from Day 5 onwards, where Day 0 is the day you returned back to the UK.
You can collect your sample anytime on or before Day 2, where Day 0 is the day you returned back to the UK.
You should collect your Day 8 sample on Day 8, where Day 0 is the day you returned back to the UK.
If you test positive for either a Day 2 or a Day 8 test, you must quarantine for a further 10 days from the day you took the test – you will receive further advice alongside your test results. Positive Day 2 tests are sent for genomic sequencing to check the strain of the virus the patient is carrying. If your test shows that you have a variant of coronavirus known as a ‘variant of concern’, you will get a further call and your close contacts will be asked to be tested.
Yes, the scheme rules state that you can attend the clinic to collect a test or have a sample collected. You are also allowed to exit your isolation address to post a sample.
No, if you have had 2 doses of a UK-approved vaccine, you only require a Day 2 test. Unvaccinated travellers will need a Day 2 and Day 8 test, with the option to end quarantine early by completing a Day 5 Test to Release PCR (quarantine can be exited upon receipt of a negative Day 5 Test to Release result).

Antibody tests require a blood sample. This can be collected by finger prick for selected tests, or via venous draw if you visit our doctors in-clinic.
For our in-clinic service, we ask that patients be aged 12 or over, and be comfortable with having blood taken. For finger prick kits there is no age limit, however, drawing blood from children is challenging and we do not recommend attempting to collect a sample from a child under the age of 12 (please note, kits are non-refundable in the event you are unable to draw blood).
Test kits are medical or healthcare items. They are unique to the individual and are not refundable. The tests can be used for up to a period of 6 months; therefore, you can keep your tests for future use in the event of cancelled travel.
No, each traveller should have a unique booking reference number. Please contact us and we will reissue.
There is a weight of evidence to show that clinician-led samples obtain a better sample of relevant genetic material for testing. However, the testing process is the same for all tests.
Your Day 2 and Day 8 tests are interchangeable, but please check with a member of our customer care team if you are unsure by sending your test barcode or unique reference number to email@example.com.
