Inr jumps from 2.9 to 4

[callum19]

My inr has now jumped high what can cause this. Have not had the greens. And my medication has been the same. I'm now on alternate 9 /10 waferine

Any advice would be appreciated. Next check is next Wednesday

Thank you

Hi Callum, INR is the blood test for warfarin.

This community is for people with thyroid problems. If you don't have a thyroid problem maybe you would get a more useful response by posting on a different community, such as one for heart problems.

From experience when my husband was on warfarin, INR may be affected by things other than greens. Try this link for info about diet when on warfarin.

All the best.
