Anticoagulant Clinic at University Hospital Lewisham

Blood Test

The anticoagulant clinic at University Hospital Lewisham is for patients who require special medication (anticoagulants) to reduce blood clotting.

Patients who have an appointment at the clinic will have their blood tested (via a finger prick) using a special Coagucheck device that provides immediate results.

Specialist software (called ‘RAID’) is then used to determine the correct dose of anticoagulant medication that the patient requires.

This process is managed by a team of doctors, nurses and pharmacists, who are also on hand to provide any advice that patients may need.

The team have close links to the Community Anticogulation Service, and some patients may be able to visit a clinic closer to their home rather than coming to hospital for all their appointments.
