Q: When a person's blood is thick what will be an average INR reading? Does an INR reading of 1.8 mean that the blood is too thick/or does it mean the blood is too thin? Please answer. Carol K
Hi Carol,
You should discuss your question with your physician, but generally, a longer-than-normal INR can mean a lack of or low level of one or more blood clotting factors, a lack of vitamin K, liver disease, etc. In addition, a longer-than-normal INR can be caused by treatment with blood-thinning medicines, such as Coumadin.
