Howard Bailey - INR Blood Test

INR (International Normalized Ratio) Blood Test. This is a measurement for the length of time it takes blood to clot. The increments of time are not measured in seconds or minutes but instead by a sort of metric time agreed upon by international medical organizations. Normally a healthy person's INR is measured at '1.0'. If a person's blood clots too quickly (less than 1.0) drugs are used to increase (lengthen) 'INR' to between 2.0 and 3.0 or longer.
Blood that clots too quickly can cause a variety of serious health issues such as thrombosis (inner vein/artery clotting), stroke or heart attack.
