The Rapid Diagnostics Centre

 142-146 Harley Street



The London Clinic estate across Harley Street covers a broad spectrum of diagnostic specialities, including Eye, Ear, Nose and Throat (ENT), Cardiology, Orthopaedics, Dermatology, Breast, Urology, and Gynaecology, with integrated cancer screenings across all areas. Specifically, the Rapid Diagnostic Centre houses dedicated diagnostic clinics for Urology, Gynaecology, Breast, and Dermatology, providing expedited and precise diagnostic services to address diverse health needs. 

While cancer diagnostics are a key focus, our aim is early detection and rapid diagnosis for all potentially life-threatening health concerns. This facilitates swift access to the right consultants and departments, so patients are diagnosed and treated faster, for a quicker recovery.

If you’re experiencing symptoms, you can contact our customer service team by calling 02076167693 or via our online web form. Our team will assist in booking you in with a specialty consultant based on your health concern. The consultant will order diagnostic tests on the same day, and you can undergo the tests within 48 hours. Results will be available within 48 hours (depending on specialty and range of tests), and the consultant will provide you with the results, discuss next steps, and if needed, arrange further procedures or treatments within The London Clinic.

If you are proactive about your health or have a history of family health concerns, you can choose a Health Assessment package or one of our self-pay screening packages. Simply call us on 02076167693 to talk to a GP who will advise on the most suitable diagnostic package and, if required, order diagnostic tests. The tests will be completed within 5 working days and the GP will provide you with the results. If a diagnostic package is not suitable for you, the GP or consultant will talk you through the best next steps. 

Yes, you can. We have a new walk-in GP service in partnership with Doctorcall and MyHealthcare Clinic available in the Rapid Diagnostic Centre. Although you can walk in and book at our reception, we advise that you call us first on 02076167693 to ensure we can fulfil your requirements.  

At your appointment the GP will order any necessary diagnostics or blood tests. You will then receive the results via phone or in-person at the clinic within 48 hours, and if needed, the GP will refer you to a consultant working at The London Clinic for further evaluation or treatment.
