According to the Virtual Medical Centre, INR stands for international normalized ratio. This system measures the amount of time that it takes for a person's blood to clot. Typically, INR is used to test the blood of people who take oral anticoagulants such as warfarin, which can significantly alter the way that blood clots.
If INR levels are too high (over 4.5), the blood becomes thinner, thereby increasing the chance of excessive bleeding. However, if INR levels are too low (below 2), the blood thickens and begins to form blood clots within the blood vessels, reports the Virtual Medical Centre. Blood clots are very dangerous, as they can lead to other serious health events, including heart attacks and strokes.
When a person initially begins taking an oral anticoagulant, a doctor should monitor his INR levels daily until the levels have been in the target range for at least two consecutive days. Afterward, the time span between tests can increase to every two to three days and eventually become as long as every four weeks, accodring to the Virtual Medical Centre.Learn more about Medical Ranges & Levels
