We are a nurse-led private testing clinic beside St Paul’s Cathedral, built for people who do not want to wait weeks for answers. Book straight in for the test you need – no referral, no registration, no hidden charges – and have your results back within days, not weeks.
Under one roof we offer more than 1,000 laboratory blood tests, 19 health screening packages from a Basic Full Body MOT to cancer-aware screens for the over-60s, a discreet sexual health clinic and comprehensive allergy testing. Samples are taken by NMC-registered nurses and processed by a UKAS-accredited laboratory, with most results back within 24 to 48 hours.
We are regulated by the Care Quality Commission, all testing is overseen by a GMC-registered doctor and every price is published up front. Your report is written clearly enough to act on – and to hand to your own doctor if anything needs follow-up.

No registration fee, no charge for prescriptions or sick notes, and every price listed before you book.

Your report highlights anything outside the reference range. We are a testing service rather than a GP practice, so the report is designed to be taken to your own doctor for interpretation and any treatment.
Only for glucose and cholesterol tests. If your package includes them we will ask you to fast for 8–12 hours – water is fine.
