Any questions?

Your reference number is MAYFI0 followed by your 6 digit receipt/invoice number issued upon booking. This should be added to your passenger locator form.

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

The scheme rules dictate 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 on Monday. Samples are sent Royal Mail Tracked 24.

Unfortunately as kits are personalised healthcare items they are non-refundable

You can collect your sample anytime from Day 5 onwards, where Day 0 is the day you returned back to the UK

For home test kits, you should return to Mayfield Clinic (Mon-Fri before 3PM) or one of our national drop points visible here: https://www.mayfieldclinic.co.... . We are unable to accept weekend returns to Mayfield Clinic, but can advise return options; please contact us via email.

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.

Yes, according to the scheme rules they do

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