Wow, that's low. It's my understanding that a level of 1.0 is equivalent to not even taking blood thinners! But I'm just a patient, not a medical expert, so I'm probably wrong!

I was dx'd at Mayo and they kept me between 2 and 3. Actually, so did my hemo here, till he handed me off to the coag clinic for routine management. I'm not nuts about the 2.5 - 3.5 stuff!
