Frequently asked questions

Your booking reference number is the number you are required to enter on your passenger locator form before travelling. 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.

Tests can be collected from Mayfield Clinic Oxford Monday-Friday 09.30-16.30, or we can dispatch by post.

The scheme rules dictate that we can only send kits on Day 4 (or they can be collected on Day 5). If Day 4 falls on a weekend, we will send the kit on Monday. Samples are sent via Royal Mail Tracked 24.

Our home-testing services require full pre-payment at the time of purchase. Home testing kits are considered personalised items and are non-refundable per the distance selling regulations. For more information, please check our T&Cs.

Please check the instructions provided in your test kit for return guidance.

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.

Individuals of all ages

There are 3 outcomes of your test:

  • Positive - You are infected with the SARS-CoV-2 virus. Please immediately follow PHE England guidance to isolate along with your household
  • Negative - You are not infected with the virus. Please continue to take sensible precautions, if you were self-isolating as an international arrival you may stop self-isolating.
  • Invalid - Occurs in 1-3% of samples. Typically (but not exclusively) this arises when insufficient human material is present on the swab sample, and is more frequent with home test kit samples. It can be mitigated by using our practitioner-led testing service. You must continue to isolate as an international arrival

Once you've collected your sample (self-test) or seen a practitioner for a sample collection, you will need to register your kit barcode according to the provided instructions. Results will be sent through to the registered email. Please check your junk mail if no results have been received at the expected time, and then contact info@mayfieldclinic.co.uk if still not resolved.

For post, your kit will be sent next working day (kits are dispatched Mon-Fri except public holidays) using Royal Mail's Tracked24 service. Please allow 1-2 days for delivery from this point. Alternatively, you can collect from Mayfield Clinic Oxford.

For comprehensive details of the scheme, please see this government webpage.

Please note that the test timeline should be considered a guideline. We have a history of returning test results on time, however occasionally issues outside of our control (e.g., courier delays, lab processing issues, laboratory supply chain issues) may mean that your sample takes longer to return. We will provide a refund should your test result be delayed past 5PM the day after it is expected.

Why use Mayfield Clinic's testing services?

In a crowded market for COVID testing services, three reasons why you should use Mayfield Clinic

Whilst no COVID-19 PCR testing is infallible, throughout the crisis, we've strived to ensure that we consistently deliver PCR coronavirus testing to meet the expectations of our customers. This has included using 7 different laboratories, shifting capacity as required to deliver the fasted and most reliable testing possible.

For our PCR Fit To Fly travel testing, we run daily point-to-point couriers from all of our testing sites directly to the laboratories. This differs from other services that might rely on postal services for Fit To Fly testing.

All of our COVID testing services are overseen by our advisory board of GMC registered general practitioners. Onsite testing services are delivered by General Practitioners or trained Healthcare Professionals. Testing is conducted under our UKAS ISO17025 accreditation and our CQC registration (applicable to our Oxford head office).
