Frequently Asked Questions

4 rated Good, and 1 without a published rating. Ratings are set by the Care Quality Commission and can change after each inspection.
Some scans and tests can be booked directly, while others — particularly where results need clinical interpretation — require a referral from a GP or consultant. The provider will tell you what is needed when you enquire.
Private diagnostics often provide results quickly, sometimes within days, but it varies by test and provider. A good clinic will explain when and how you will receive results and will share them with your GP or specialist where appropriate.
Check that the provider is registered with the Care Quality Commission, and for laboratory testing look for UKAS accreditation. Remember that a scan or test is only as useful as the clinical interpretation behind it — discuss results with a qualified clinician.
