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.

Home from hospital today. Had a spinal fusion done on Monday. L5 S1. I was off Pradaxa for 10 days, which was a bit nerve wracking.  But back on tonight. Seems surgery went well, and I am able to take short walks. My thanks to the surgeon and staff.

Hello, ladies. Know I've been away quite a while. Guess you could say that things have been somewhat busy; the usual chores and daily things and such. Hope all's well with you and everyone else on the forum. My heart is basically the same, not too weaker and, of course, not too much stronger, either. Generally the same. The defibrillator keeps a close eye on my heart rhythm. I thank God for this day especially because it is my birthday. I made it to 54 years because of God's grace and mercy. You all take care of yourselves and we'll talk again soon.

Anyone have experience with this? I began a low dose  of topamax this past week , at the direction of my neurologist, and approval of my EP, for essential tremors that have become worse over the past two years since my diagnosis of afib and aflutter. The usual beta blockers aren’t a good option for me as I am bradycardia except when in afib or aflutter. Today when I took the first full dose of 50 mg I knew I was in trouble as I felt OFF all day and finally as my rhythm med wore off went into full blown aflutter with HR of 148. After an hour of deep breathing,drinking water,  etc, I felt close enough to-my next dose of  Tikosyn so I took it, as well as my dose of Magnesium and within half an hour I was in synus rhythm. I have not had an episode for many months and have no doubt what started it. I am upset that i had no warning..but perhaps I am the outlier. Anyone else? And what do I do with this information? And no I will not ease myself off this..I am done! It was awful!
