Why test INR levels at home?

Patients on warfarin need to get their INR levels measured regularly, which often involves visiting a local anticoagulation clinic, lab, or doctor’s office to get a blood test. However, there’s another option for INR testing: in-home testing, also known as self-testing or point-of-care testing.

In conclusion, it allows patients to test their INR levels without the need for frequent visits to a lab. In-home testing only requires a finger stick, instead of a full blood sample. In-home testing may lead to fewer blood clots.
