Putting people first is why we exist

We're a small group of doctors and business leaders who created C19 Testing because we believed that people deserved transparency, honesty and certainty when having to take unfamiliar tests in uncertain times.

We believe that there is a "right" way to provide testing that puts people ahead of profits. Everything we do is orientated around delivering a great service that protects our customers.

We're advocates for responsible medical testing and have the following guiding principles:

Indication: We will give clear information on who a test is recommended for and why it is recommended.

Evidence: All the tests we offer are routinely used by doctors in the UK and have appropriate regulatory approval.

Necessity: We will never recommend that tests are performed more often than is necessary.

Quality: We only partner with laboratories that are accredited and regulated for tests they perform.

Interpretation: We will always provide the information you need to interpret your results and take appropriate action.
