Anticoagulation (warfarin) Monitoring Services
We see patients who need regular monitoring of their blood thinning medication.
Our service is for patients registered with a GP in Buckinghamshire who take warfarin or sinthrome.
Why do I need anticoagulation monitoring?
You may also need to take blood thinning medication to prevent a blood clot if you’re at high risk of having them in the future.
The aim of treatment with warfarin or sinthrome is to thin your blood but not stop it clotting completely. Getting this balance right means your dose of warfarin must be carefully monitored.
Do I need a referral?
Yes. Your GP or a hospital consultant will refer you for anticoagulation monitoring.
Where do I need to go for anticoagulation monitoring?
You can choose where to go. Your GP can refer you to a service that’s closer to your home if that’s more convenient.
We run clinics by appointment only at Wycombe and Stoke Mandeville Hospitals, as well as at our community hospitals, health centres and GP surgeries across Buckinghamshire.
What happens during my appointment?
A specially trained nurse or healthcare professional will take a drop of blood from your fingertip using a finger-prick test known as an International Normalised Ratio (INR). This tells us the dose amount of anticoagulant medication that you need to take in between blood tests.
Your results will be available straight away. This means that you’ll get your INR results, warfarin dose and next appointment at the same time as your visit.
How often do I need to attend an anticoagulant clinic?
It depends on your INR. You may need to attend a clinic every few days to begin with until your INR stabilises and you’re on the right dose of medication.
