What does 0.9 level of PT/INR value indicate?
human
Hi, I had a PT/INR done on Friday and results came back with a 0.9 . I have been taking 7.5 mg of warfarin daily and my doctor advised me to double the dose and take another PT/INR on Wednesday.What I want to know is what dangers do I need to be aware of with my levels being 0.9 ?

hello,PT/INT is prothrombin time international ratio that measures the coagulating capacity of the plasma. Conditions like warfarin doses, vitamin K deficiency, liver disease, etc raises PT INR value. It's normal value is 0.8-1.2, however with ongoing warfarin, a value of upto 2.5 is acceptable, rather maintaing high INR is our intention when on warfarin therapy.The reason for which you have been on warfarin, is what I would need to know before making further comments.hope to have satisfied your query.Regards,Dr Pankaj Borade
