RefluxUK Physiology Service
Our national, medically-led physiology service is available to any clinician looking to refer a patient for upper-GI diagnostic tests
Our mission
RefluxUK offers a medically-led gastrointestinal physiology service, performed by experienced clinical scientists and results co-reported by leading consultant gastroenterologists.
We encourage our referrers to discuss patient results with our reporting clinicians and offer an MDT with leading experts from across the UK. We believe that this model of collaboration and communication provides referring consultants the opportunity to maximise the clinical value provided by physiology testing.
How to refer
Clinicians can use the below form to submit their referral to our administrator, who will confirm receipt and contact the patient directly.

Refer for ConsultationTests Provided
- High-Resolution Manometry
- 24-hour PH/Impedance Monitoring
- SIBO Breath Tests (home test-kit)
We accept any self-funding patients, or those covered by all major insurers.
Please note, insurers tend to require a referral from a gastroenterologist/upper GI surgeon for these tests to be covered.

Our Comprehensive Service
Upon receiving a referral, our Patient Care Coordinators will contact your patient to organise their appointment, removing any work required by yourself or your adminstrative team:
- Discuss with the patient what to expect, how to prepare and confirm their booking at a time and location that suits them
- Take payment, insurance details or assist in finance options
- Rapid reporting, sent directly back to you

Access to the Experts
RefluxUK is unique in offering access to our physiologists, gastroenterologists, surgeons and other experts, should you wish to discuss your patients' reports further:
- 1:1 discussion of results and their interpretation with our reporting clinicians
- Our national, monthly MDT for an in-depth discussion with leading experts on the report and potential medical or interventional treatment options
