Monitoring Anticoagulation at Home

Monitoring Anticoagulation at Home

Are there any options for do-it-yourself monitoring?


While most people on warfarin or Coumadin® go to an anticoagulation clinic to monitor and test their blood’s clotting time, some people are able to do their own testing and monitoring from home. People who do so may feel a greater sense of control and ability to take part in managing their own care. This option is especially valuable for people who maintain a full schedule, enjoy traveling, or have other reasons that make it difficult to get to the clinic. The need for testing and monitoring at home only applies to people taking warfarin or Coumadin® for stroke risk reduction using anticoagulation medication; NOACs do not require testing.

Who is a good candidate for at-home anticoagulation monitoring?


If you have been diagnosed with atrial fibrillation and have been taking warfarin or Coumadin® for at least 90 days, you may be eligible to begin testing your INR or clotting time (also called Prothrombin time) from home. If you’re interested and willing to manage your part of the process, your healthcare provider can submit a request to authorize you to complete your testing and monitoring requirements from home. From there, you’ll work with your insurance provider or national healthcare benefits program to arrange for any necessary payments and connect you with a monitoring company that will provide the equipment and teach you the steps for timely and accurate measurement.

What is the process for at-home monitoring?


Most medical coverage options allow for weekly or bi-weekly testing, and the testing must usually be communicated back to the monitoring company who then communicates it to your doctor so that you can maintain a prescription for your medication. The monitoring company will alert your healthcare provider if results of your blood clotting time are out-of-range so your doctor can promptly adjust your dosage. This regular communication also allows the monitoring company to track your usage and send additional supplies when your usage data indicates you should be running low, which will save you time and energy.

People who monitor at home will likely want to create a convenient place for storing supplies, testing, and reporting results. During training, your monitoring company may help you work out a system to remind yourself when it’s time to test.

Hi everyone.

My mother (65 years old) was recently diagnosed with Atrial Fibrillation. She had a holter ECG exam and the report concludes with: "Frequent episodes of non sustained atrial tachycardia. Atrial fibrillation lasting more than one hour during sleep. No significant pauses. No symptoms". I attach the full page of the report. 

She had fainted for brief moment in 2012 and 2017 for not obvious reasons. Early this month, she fainted again for a few seconds. This time she checked with a doctor who then referred her to an arrhythmia specialist. The specialist then did this holter ECG exam on her. 

The specialist says that it's tricky to give her medicine in this patient's case (my mother). The specialist recommends a pacemaker implant or ablation. The specialist also mentions that this condition (atrial fibrillation) increases the risk of stroke. 

My mother was also diagnosed with atrial septal aneurysm Labile hypertension in 2008. Otherwise she has good cardiac health (no cholesterol, ideal weight, doesn't smoke etc). Her general health is also good.

We're especially concerned with increased risk of stroke. That's why we're okay with the pacemaker option if that is the effective option (to prevent stroke). But we also wonder a little bit if we should try medicine first. You have much more experience with this condition, what do you think?

New study finds that 84% of those that receive an AF notification on the watch were diagnosed with AF.  Pretty accurate and the accuracy is improving.  Something to think about.
