Covid-19 YourHealthFirst Clinic

An antigen test is used to aid with the rapid diagnosis of COVID-19 by detecting the presence of the SARS-CoV-2 nucleocapsid protein antigen. This is different to the lab molecular test which uses RT-PCR (in simple terms, RT-PCR looks for the genetic part of the virus (RNA), while antigen testing looks for a protein particle of the virus).
We have carefully selected an antigen test which is public health assessed. Compared to PCR, our test shows a sensitivity of 98.56% and a specificity of greater than 99%. We have carefully followed research and government advice in our testing processes. Please note that no current Covid 19 tests are 100% accurate.
We are currently providing Antigen testing in partnership with multiple pharmacies across London. You simply book and pay for the test online, at which point you will receive an email with full instructions and details of where to go.

Our Antigen test is a rapid swab test, CE marked that detects specific proteins (antigens) on the surface of the COVID-19 virus. Results are available within 15 minutes!
