INR Clinic

INR Tests During COVID-19

If you currently take Warfarin, it is essential we still take your INR in order to dose your medication. This is considered an essential trip from your home. Our INR Clinic is currently being held at our branch site, Chapel Surgery. Please telephone the surgery one day before you are due in order to book your appointment for the following day.

On the day of your appointment, please if you are able to travel and attend your appointment alone please do so, unless of course you need assistance, one other can accompany you. We ask that you wait in the car park. Please provide us with your mobile number so we can give you a call when the Healthcare Assistant is ready to see you. If you do not have a mobile please let us know at the time of booking and do not attend your appointment early, a member of staff will come out to the car park and call you in to the building. 

We thank you for patience and co-operation at this time.

INR Clinic 

The INR Clinic is run at our main site, Eryl Surgery on Tuesday mornings and Thursday afternoons. The clinic provides regular check-ups with the Health Care Assistant or Practice Nurse providing monitoring for patients on long-term and on lifetime anti-coagulation therapy to measure their INR levels. 

Our clinic is run by our Healthcare Assistant:

Mrs Kirsty Stabler  

Warfarin is an oral anticoagulant medication which “thins your blood”.

People taking Warfarin need regular monitoring using a blood test called “INR”. This stands for International Normalised Ratio and allows us to maintain the ratio within a set target range. It is performed by a finger prick test with the result available within 2 minutes so that we can adjust the dose of Warfarin accordingly.

There are many factors that can affect the INR ratio including certain medications which are prescribed and those that can be bought over the counter. If you are prescribed Warfarin and have to take any other medication – either prescribed or purchased over the counter – you must tell the Prescriber or Pharmacist that you take Warfarin. If you start other medications such as Antibiotics it is important you check your INR levels before and after your course. 

Similarly, certain foods and drinks can affect the way your Warfarin is metabolised and cause the ratio to fall or rise.

A list of these foods can be obtained by visiting this website: NHS Choices- Anticoagulants

Further information can also be sought during your clinic appointment.

It is vital that you attend your appointment as instructed by the HCA or clinic nurse. 

We understand other commitments can arise and we always try our upmost to accommodate and re-schedule your appointment within a clinic time that suits you. At the clinic you will be provided with an Anti-coagulation Log Book in order to keep track; keep  an up to date record of your INR readings and what dose you need to take until your future appointment date.
