Difference Between Pt and Ptt

Main difference

PTT and PT abbreviated as ‘partial thromboplastin time’ and ‘prothrombin time’ respectively are the two types of tests that are done to check the time it takes for blood to clot. Both of these tests are essential for diagnosing blood quality and can also alert you to excessive blood loss in the event of injury if not enough blood clots form. The PTT test is the measurement of the intrinsic coagulation pathway along with the common coagulation pathway. On the other hand, PT is also known as INR (International Normalized Ratio), which measures the ratio of prothrombin; it also checks whether or not medications to prevent clotting are working.Most of the time, these two tests to check for bleeding problems are done at the same time.

What is Pt?

PT (prothrombin time) is the test that is done to assess the time it takes for blood to clot; it is an essential test to check for bleeding problems. If the blood already coagulates enough to the point that it can cause serious health problems, in PT, it is observed whether or not the medications taken to prevent blood clotting are working properly. It will be relevant to mention here that blood coagulation saves lives and is healthy as it prevents excessive blood loss during injuries or any surgery, but at the same time, abnormal blood coagulation can bring serious problems such as heart attack. heart and stroke The prothrombin test is also called the international normalized ratio (INR), since in this case, the standard prothrombin time test is performed independently of the test methods. The INR test allows your doctor to examine the prothrombin test, even if it came from a different lab using a different technique. Due to the standard verification of the INR test, some of the laboratories only give the INR tests. In this test, coagulation factors such as I, II, V, VII, and X are examined. In the PT test, the level of warfarin and vitamin K in the blood are also tested, for more compact results. As we know, this test reports the time it takes for the blood to clot; it normally takes 11 to 16 seconds if you are not using any medication. If your blood does not clot within the normal time, you may be suffering from vitamin K deficiency or even using the wrong dose of warfarin. some of the laboratories only give the INR tests. In this test, coagulation factors such as I, II, V, VII, and X are examined.

What is PTT?

Partial thromboplastin time (PTT) is another blood test that measures the time it takes for blood to clot. In other words, we can say that it assesses the body’s ability to form blood clots to prevent excessive loss in the event of injury or during surgery. In PTT, the level of heparin in the body is also examined, as drugs like this can cause blood thinning. This test investigates factors that influence excessive bleeding or clotting; although it works at the initial level and if abnormalities are found, several more tests can be derived to better understand the state of the blood. The PTT assesses hemostasis, which is the process of blood clot formation and the prevention of excessive blood loss due to injury. The coagulation factors that are examined in PTT are I, II, V, VIII, IX, X, XI, and XII. And the normal value taken from these tests is between 25 and 35 seconds. Taking medications such as warfarin, heparin, and aspirin prior to testing can affect the test, so it is often recommended that these medications be omitted before administering samples for testing.

Pt vs. Ptt

  • PT is abbreviated as ‘prothrombin time’ while PTT is abbreviated as ‘partial thromboplastin time’.
  • In PT, the measurement of the prothrombin ratio is done together with the INR (International Normalized Ratio). On the other hand, in PTT, the measurement of the intrinsic coagulation pathway is performed together with the coagulation pathway.
  • In PTT, the level of heparin in the body is closely measured, while in PT, the level of warfarin and the level of vitamin K are evaluated for better tests.
  • The normal PT result is 11 to 16 seconds, while the normal PTT result is 25 to 39 seconds.
