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).

The VirTus test provides a quantitative score for both IgG (long-term) and IgM (short-term) antibody levels, and interpretation as to whether levels are Very high, High, Med or Low. The Roche provides one score for overall antibody level, and no interpretation

What tests we offer

We offer two antibody tests to identify past infection with SARS-CoV-2 (COVID-19) and/or response to SARS-CoV-2 vaccinations. The tests available are developed by Roche and VirTus (an Imperial College London spin-out).

Both tests detect antibodies developed in response to the vaccines in use in the UK as part of the NHS' vaccine program. They utilise the receptor binding domain (RBD) of Spike antigen, whereas traditional antibody tests seek the nucleocapsid.
