Prothrombin is a protein made by the liver. Prothrombin helps blood to clot. The “prothrombin time” (PT) is one way of measuring how long it takes blood to form a clot, and it is measured in seconds (such as 13.2 seconds). A normal PT indicates that a normal amount of blood-clotting protein is available.
