Prothrombin time (PT) measures the activity of coagulation factors in the tissue factor pathway of the coagulation cascade.

Factor VIII is crucial in the intrinsic pathway of the blood coagulation system. It helps in the activation of factor X, which is a key step in the formation of a blood clot. Without factor VIII, this pathway would be impaired, leading to difficulties in clot formation.
PT (prothrombin time) and PTT (partial thromboplastin time) tests are used to monitor the function of the blood clotting system and to assess the risk of bleeding or clotting disorders. PT is generally used to monitor the effectiveness of anticoagulant therapy, while PTT is used to evaluate the intrinsic pathway of coagulation and monitor heparin therapy.
Generally precious metals as Au, Ag, Pt, Pd, Ir.
Yes, coagulation begins with vasoconstriction and the formation of a platelet plug at the site of injury. This is followed by activation of clotting factors leading to the formation of a stable fibrin clot to stop bleeding.
The prothrombin time (PT) test measures how long it takes for blood to clot. This test evaluates the coagulation factors involved in the extrinsic pathway.

As most coagulation factor proteins are produced in the liver, any disease of the liver will have an effect on the levels of coagulation factors, and in turn the patients' ability to form a clot. Therefore it is normal for a patient with liver problems to have a prolonged PT The in vitro test of PT tests for deficiencies of factors I, II, VII & X. If your aPTT was normal, the deficient factor will be VII, as deficiency in others would have had an effect on the aPTT too
It may mean that the patient has a vitamin K deficiency, a liver disease, or disseminated intravascular coagulation (DIC).
A lavender or pink top tube is typically used for a PT (prothrombin time) test. This is the color used for collecting samples for coagulation studies.
A coagulation cascade is the sequence of biochemical activities, involving clotting factors, that stop bleeding by forming a clot.
Yes, "pt 13.3" typically refers to a prothrombin time (PT) of 13.3 seconds. Prothrombin time is a blood test that measures how long it takes for blood to clot and is often used to evaluate the coagulation system. A PT result can help assess the risk of bleeding or clotting disorders.
