If you are on warfarin you will need your International Normalised Ratio (INR) blood level done regularly in our INR clinic. The INR or International Normalised Ratio is the measurement of blood clotting time, for more information please visit NHS.
We run one-stop INR clinics twice weekly, on a Tuesday and Friday morning.
Patients on warfarin will be invited to attend, have their finger pricked and the blood tested to determine their clotting (INR) level. The nurse will then alter the dose of warfarin if necessary and arrange the next appointment.
