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 and APTT are two types of test conducted to measure the coagulation of blood in the patient. INR stands for âInternational Normalized Ratioâ. It is also called âProTime INRâ and âINR PTâ. APTT, on the other hand, stands for âActivated Partial Thromboplastin Timeâ. The international normalized ratio is derived form the prothrombin time (PT) and the prothrombin ratio (PR). These are used to measure the extrinsic pathway of coagulation.
