INR Service

The INR Service provides  high quality “one stop shop” monitoring, initiation and education for Adult patients taking Oral Vitamin K Antagonists (Warfarin, Sinthrome and Phenindione) following a referral from GP or hospital consultant, and where this service is not provided by their own GP.

The service runs from three hubs based in Lincoln, Gainsborough and Grantham. Patients can access satellite clinics throughout Lincolnshire, the service has 17 different clinics each week and patients can attend clinics which are closest to their home or is most convenient.

Clinics run from Monday to Thursday with clinical staff available on Friday for advice and support (excluding bank holidays).

A domiciliary service is also available for house bound patients only – any enquiries regarding this then please contact the service.

Patients who are visiting the area and require an INR test will need to temporarily register with a GP and request referral to the service. It is essential that this is be done before they can be seen.
