PT (Prothrombin Time) Test
The prothrombin time test is an investigation to measure blood clotting. The prothrombin time test is vital. The prothrombin time helps to know how long it may take for your blood to clot. It may be known as PT or pro time test. Prothrombin is a protein synthesised by your liver. Prothrombin is one of the clotting factors. It is also known as clotting factor 2. It may be one of the factors in your blood that helps blood clot or coagulate.
The prothrombin time test may also be performed to diagnose liver disease. It may be a prime test for liver transplant patients. The prothrombin time is denoted as the international normalised ratio (INR). An abnormal prothrombin time may be due to liver disorders or anticoagulant or blood thinner medication.
