Coagulation monitoring

Quality care for your patients taking vitamin K antagonists

Vitamin K antagonists (VKAs) require close monitoring because of individual variations, drug-drug or food-drug interactions.1 Studies have shown that increasing a patient’s time in therapeutic range, as measured by their international normalized ratio (INR) value, maximizes the benefits of anticoagulation therapy and minimizes the risk of thromboembolic events.2-4 Therefore, keeping careful track of your patient's INR value to ensure it is in the optimal therapeutic range is critical.

Models of patient monitoring

 

Enhance efficiency for you and freedom for your patient

 

A variety of models exists for managing patients of VKA therapy.  Learn more about the benefits of point of care and patient self-testing and how we can support you in selecting the right model for you and your patients. 

Blood test
Traditional or usual care

 

Performed by a conventional laboratory. Results can take hours if not overnight to be returned to the physician. The healthcare professional interprets the result and, if needed, changes the patient’s dosage. The patient may have to wait for the results, or even return to the physician after the result is delivered. 

Patient with nurse
Point of care testing

 

Performed by healthcare professionals immediately at the patient point of care. CoaguChek offers reliable and easy to use solutions that provide immediate results. Thus, allowing treatment decisions to be made more quickly.

Patient testing at home
Patient self-testing

 

Together with you, properly trained patients and/or caregivers are capable of performing reliable INR testing themselves. This method of coagulation monitoring may provide some patients with the maximum amount of freedom to suit their testing needs.
