If you are on oral anticoagulation therapy, you understand the importance of frequent prothrombin time/international normalized ratio (PT/INR) monitoring. Frequent monitoring allows your physician to adjust your medication dosage to keep your PT/INR in target range, which lowers your risk of complications, such as clots or bleeding1.
Frequent monitoring doesn’t have to mean frequent trips to the doctor or clinic. Many patients are able to self-test and report their results from home. This site can help answer questions you may have about patient self-testing (PST). Then, talk with your physician to see if it’s right for you.
- 77 percent of patients preferred self-testing with a CoaguChek system over clinic testing2 which explains why PT/INR self-testing more than doubled nationwide from 2009 to 20113.
