Prothrombin Time Performed On Site at UHealth Jackson Urgent Care — Country Walk
Prothrombin time (PT) is a blood test that measures the amount of time it takes for the liquid component of the blood to thicken and clot (prothrombin is a plasma protein that is involved in the clotting process). Oftentimes, this test is used to monitor a patient who is taking blood-thinning medications, such as warfarin, to help maintain an appropriate balance between preventing blood clots and allowing excessive bleeding. PT can also be used to help a physician determine the cause of unexplained bleeding or bruising, detect a clotting or bleeding disorder, or evaluate liver function.
Prothrombin time can be performed on site at UHealth Jackson Urgent Care – Country Walk. The test involves a simple blood draw, usually from an arm or hand. A laboratory specialist will then add special chemicals to the blood sample and record the amount of time it takes for a clot to form. The chemicals activate the coagulation factors in a sequence of steps known as the coagulation cascade, which leads to clot formation.
At UHealth Jackson Urgent Care – Country Walk, we report prothrombin time results in the form of an international normalized ratio (PT INR) to ensure uniformity across testing methods for comparison purposes. In addition to monitoring the effectiveness of medications, a physician can use prothrombin time to help diagnose certain genetic disorders and other conditions that can affect blood clotting.
In many cases, no specific preparations are necessary for a prothrombin time test, so it can often be performed at UHealth Jackson Urgent Care – Country Walk on a walk-in basis. However, certain consumed substances, such as alcohol, antibiotics, hormones, and supplements can affect PT. Therefore, in order to ensure that the results are interpreted and used correctly, it’s important to inform your healthcare provider about the use of any prescription or over-the-counter medications, vitamins, supplements, or herbal remedies.
