It is formed in the liver
Prothrombin is converted to thrombin by the enzyme thromboplastin. Thrombin plays a vital role in the clotting cascade by converting fibrinogen into fibrin, which forms a mesh that helps stop bleeding.
Prothrombin time (PT) measures the activity of coagulation factors in the tissue factor pathway of the coagulation cascade.
An increase in prothrombin levels can lead to an increased risk of blood clot formation (thrombosis). This may put individuals at risk for conditions such as deep vein thrombosis and pulmonary embolism. Monitoring prothrombin levels is important in managing clotting disorders and preventing associated complications.
Prothrombin is a soluble protein found in blood plasma. It plays a key role in the blood clotting process by being converted into thrombin, which helps form a blood clot.
Dimedone is synthesized from mesityl oxide and diethyl malonate .
Protein factors required for clotting are synthesized by the liver. These proteins include fibrinogen, prothrombin, and factors V, VII, VIII, IX, X, XI, and XII. Their synthesis is regulated by various factors including vitamin K.
prothrombin time, hematocrit
The INR has basically replaced the prothrombin time, or PT.
Prothrombin is converted to thrombin by the enzyme thromboplastin. Thrombin plays a vital role in the clotting cascade by converting fibrinogen into fibrin, which forms a mesh that helps stop bleeding.
The prothrombin test specifically evaluates the presence of factors VIIa, V, and X, prothrombin, and fibrinogen.

Thromboplastin -> Prothrombin -> Thrombin -> Fibrinogen -> Fibrin
Vitamin K corrects prothrombin in the setting of biliary obstruction but not of hepatocellular damage.
