About us
Anticoagulants (blood thinning drugs) are medicines that help prevent blood clots. They’re given to people at high risk of getting blood clots, to reduce their chances of developing serious conditions, such as strokes, heart attacks and to people who have already developed a deep vein thrombosis or pulmonary embolism.
Patients will be referred into our service by their GP or by a hospital A&E or inpatient ward.
What happens at your appointment
We monitor your international normalized ratio (INR), this is the time it takes the blood to clot on a regular basis and adjust the levels of medication you take (we will help you to take the right dosage of drugs like warfarin as part of your treatment for conditions such as:
- atrial fibrillation, a heart condition that causes an irregular and often abnormally fast heart rate
- deep vein thrombosis, a blood clot that develops within a deep vein in the body, usually in the leg, or after heart valve repair or replacement surgery

Patients should bring their blue mailer and report to phlebotomy who will give them a ticket to wait for the test.
The Outpatients phlebotomy service is open Monday to Friday 8.30am – 4.45pm. We ask that patients have their test by 2pm at the latest to allow us to get the result and do their dosing on the same day.
