What is Pt?
PT (Prothrombin Time) is the test that is conducted to assess the time taken for the blood to clot; it is an essential test to examine the bleeding problems. If the blood already quite clots to the extent that it can cause the severe health issues, in PT, it is observed that whether the medications taken to prevent the blood clotting are working rightly or not. It will be relevant to mention here that, blood clotting is life-saving and healthy as it refrains from excessive blood loss during injuries or any surgery, but at the same time the abnormal clotting of the blood can bring the severe issues like heart attack and stroke. The prothrombin Test is also called the International Normalized Ratio (INR) as in this the standard prothrombin time test is conducted regardless of the testing methods. The INR test lets your doctor examine the prothrombin test even it has come from the different lab with using the different technique. Due to the standard verification of the INR test, some of the labs only give the INR tests. In this test, the clotting factors like I, II, V, VII, and X are examined. In the PT test, the warfarin and vitamin K level in the blood is also evaluated, to come up with the more compact results. As we know that this test tells about the time taken for the blood to clot; normally it takes 11 to 16 seconds if you are not using any medicines. If your blood doesn’t clot as per the normal time, then you might be suffering from the vitamin K deficiency or even be using the wrong dose of the warfarin.
What is Ptt?
Partial Thromboplastin Time (PTT) is another blood test that measures the time taken by the blood to clot. In other words, we can say that it assess the ability of the body to form blood clots to avoid the excessive loss in case of any injury or during the surgery. In PTT, the level of the heparin in the body is also examined as medications such like this can cause the thinning of the blood. This test investigates the factors working out for the excessive bleeding or the clotting; although it works at the initial level and if any abnormalities found several more tests can be referred for better knowing about the condition of the blood. The PTT evaluates the hemostasis, which is the process of blood clot formation and preventing the excessive blood loss due to an injury. The clotting 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 in between the 25 to 35 seconds. The intake of the medicines like warfarin, heparin, and aspirin before the test can affect the test, so it is it is often advised to skip these medicines before giving the samples for test.
