What is the partial thromboplastin time?

Partial thromboplastin test (PTT) is a type of blood test that is usually performed to check patients with possible problems with bleeding and monitoring patients taking anticoaguants. It is also often performed to assess patients who are about to undergo surgery to prevent bleeding complications during surgery. This test is sometimes referred to as an activated partial thromboplastin time (APTT), measuring the time when a blood clot can form.

The normal result for partial thromboplastin time test is usually between 30 and 45 seconds. This may sometimes vary between laboratory depending on the methods they use. Those who use anticoagulants often have a longer time of precipitation, approximately twice as long as those who do not do so. Other diseases associated with longer partial thromboplastin are liver disease, vitamin K deficiency and kidney disorders. Longer precipitation time is also a sign of lack of factor clotting.

There are about 13 deducting factorsBloods, usually referred to as factor 1, factor 2, etc., are mostly formed by proteins operating in the sequential pattern to form a clot. Patients with bleeding problems such as haemophilia and hypofibrinogenemia usually have shortcomings or defects in one of their blood clotting factors. Hemophilia is a hereditary disease in which people usually lack factor 8 or factor 9. Hypofibrinogenemia is another inherited disease caused by a lack of factor 1. In both conditions there is a tendency for longer bleeding and losing large amounts of blood in injuries and trauma.

Patients with deep venous thrombosis and myocardial infarction are often administered by anticoagulants for treatment. Deep venous thrombosis is the formation of clots in the blood vessels of the foot, which often leads to pain and swelling of the affected area. Myocardial infarction of a or infarction usually occurs when a blood vessel supplying blood to the heart muscles is blocked by a clot. These patients are usually performed partialThromboplastin time tests to monitor these patients and check that the dose of medicine is suitable.

Another test, called Protrombin Time (PT), is also often performed together with partial thromboplastin time. Both tests are usually performed in the laboratory after the technician draws a blood sample from the patient. The risks associated with the process of using blood samples include injection infection, mild pain, pulsation and lightness.
