Hi Katherina,

Just to share part of my experience with you. My first F8 test result was absurdly high - 400+ - almost didn't survive that but I did. My F8 was tested several times after that and it did drop after a several months. In my case, the reason it dropped was because of recovery from trauma back injury. After a few years, we stopped testing because it settled in the same neighborhood as yours, which is still plenty elevated. At that point, we figured it wouldn't improve much more and was the "real deal" elevated F8 condition. I was on coumadin for many years but switched to Xarelto a few years ago so I could have my green leafy veggies back.

As Sue mentioned, what other tests they do will depend on your specific situation.

I don't know if living in a high altitude increases the risk of clots or PE but you did remind me that I had to promise that I wouldn't go deep sea diving or jump out of airplanes. I left to door open for hot air ballooning. LOL.
