It usually takes from 24 to 72 hours for healthy people to completely digest food and eliminate waste products. The first stop for food is the esophagus, which moves food from the back of the throat to the stomach. About six to eight hours after eating, food passes through the stomach and small intestine.
Prothrombin time (PT) is a blood test that measures how long it takes blood to clot. A prothrombin time test can be used to check for bleeding problems. PT is also used to check whether medicine to prevent blood clots is working. A PT test may also be called an INR test.
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). normal INR is approximately 1.0. People taking the blood thinner warfarin typically have a target INR of 2.0 to 3.0. People with an INR higher than the normal range who arenât taking warfarin may have a medical condition that needs further evaluation. A low INR is rarely significant.
