Notice that in this case (as in many cases), population does not refer to people, but to bags of potato chips. To be concise, researchers often use symbols in place of words. Greek letters are usually used when referring to populations (the entire group being studied, from which a sample or samples will be drawn).
INR (international normalized ratio) tests are important in helping your healthcare provider determine your response to COUMADIN. INR tests check to see how fast your blood clots. The INR test is primarily used to monitor warfarin therapy, where the aim is to maintain an INR in target range. Your healthcare provider will decide what INR numbers are best for you and may adjust your dose of COUMADIN to keep your INR in your target range.
INR stands for international normalized ratio. The INR provides some information about a personâs bloodâs tendency to clot (which is often described as how âthinâ or âthickâ their blood is). The INR comes from the conversion of another value, the prothrombin time (PT). Prothrombin time is the time it takes for blood to clot in a test tube. A high or low PT can suggest bleeding or clotting tendencies. Most often, the PT is checked to monitor a personâs response to blood thinners such as warfarin (Coumadin).
