What INR is normal for a healthy person?

If you are completely healthy what should your INR be?

If you are on blood thinners what range should your INR be in?

I am so confused on the ranges. Thank you for your help.

Re: What INR is normal for a healthy person?

A normal person should have an INR of 1, if I understand how it works correctly.

For clots, people on blood thinners usually are on a range of 2.0-3.0, with a target of 2.5.

For mechanical heart valves, I think the range is 2.5-3.5 with a target of 3.0.

It can go anywhere from 2.0-4.0.

Going much higher than that can get dangerous, as it can lead to bleeding complications internally. I don't think a person would typically have an INR lower than 1, unless they were packing down the vitamin K.

Thank you. My daugher's INR was 1.1, but the doctor wanted another 10 days of Lovenox shots along with Warfarin. I was really concerned thinking that her blood was super thick.

1.3 still consider as normal for some laboratory for healthy person. 1.3-1.5 is high but not a red light sign, above 1.5 without Warfarin/Coumadin intake will be concerned by the doctor.
