LifeBridge Health Anticoagulation Clinic

LifeBridge Health's Anticoagulation Clinics monitor adult patients who are at risk for blood clots and must take anticoagulant medications, also known as blood thinners.

Anticoagulants keep unwanted clots from forming in the blood. This prevents major complications such as vessel or valve obstruction, which could lead to heart attack, stroke or pulmonary embolisms. However, it's important that blood can still clot when patients receive injuries such as cuts or wounds. Therefore, the clinic is available to check patients' blood clotting ability regularly to determine the proper amount of medication they should receive.

Each time a patient visits one of our clinics, a few drops of blood are taken from his or her finger for a prothrombin time (PT) test. This test measures how quickly the blood clots. The PT is then converted to a standard unit called an international normalized ratio (INR).

Depending on the results of the PT/INR test, a patient's dose of warfarin may be adjusted to keep INR in a target range. Sickness, diet, other medications (prescription and over-the-counter) or physical activity may affect PT/INR. For this reason, anticoagulation patients must tell their health care providers about changes in their health, medicines or lifestyle.

If a patient's warfarin dose is changed, he or she will be given new written instructions. It is important that patients keep an adequate supply of warfarin on hand at all times and always follow the dosage instructions from their most recent visit.

People taking anticoagulant medication should carry an identification card and/or wear a MedicAlert bracelet indicating that they are taking warfarin. It is also advisable to carry a list of all medications currently being taken along with their dosages.
