Answer:
Option C, PTT (prothrombin time)
Explanation:
Prothrombin time (PTT) is a measure of how quickly the blood clots when a sample is drawn for analysis. When this value is elevated, it is an indication that the blood is taking longer than normal to form a clot, and the opposite is also true -- lower value means quicker clotting time. In normal conditions, PTT has an expected range of between 11 and 13.5 seconds.
Because it can measure how long blood takes to clot, this test is used to measure anticoagulation therapies, such as the effectiveness of warfarin (brand name Coumadin) or heparin; these are medications that purposefully decrease the blood's ability to form clots, so elevated PTT would reflect that the medication is working.
The PTT (Prothrombin Time) test is used to monitor anticoagulation therapy, ensuring the correct adjustment of anticoagulants like heparin.
The test used to monitor anticoagulation therapy is PTT (Prothrombin Time). This test measures the time it takes for plasma, the liquid portion of the blood, to form a clot. This test is critical as it helps healthcare providers to adjust the dose of anticoagulants, such as heparin, to ensure that a patient has a reduced risk of excessive bleeding or clotting during and after procedures like surgeries.
