I am due to have an AF Ablation on Monday. My latest INR no. has come back today at 3.1 . I was told it needs to be 2 - 3 and preferably in the 2.5 - 3 range . I have to ring the hospital if it is out of range ,which I obviously will do but does anybody know if this 0.1 over will be acceptable? I do have 3 days to get it to drop a little. I am desperate for the ablation to go ahead and am worried that it might be cancelled . Please does anyone know if the 2-3 is set in stone- so to speak .Grateful for any feedback.
