Description
Prothrombin time (PT) is the coagulation process initiated by thromboplastin, released from damaged tissues, and is recreated in the laboratory. It is the time it takes for plasma to clot after the addition of thromboplastin and calcium chloride. INR (prothrombin ratio) is another way of expressing the prothrombin time result, recommended by the WHO.
Importance of the test: one of the coagulation system tests, indicating a possible deficiency of factor VII or vitamin K, monitoring treatment with oral anticoagulants (coumarin derivatives, e.g., acenocoumarol, sintrom, syncomar), and a follow-up examination before planned surgery. Abnormal values: in kidney disease, in the absence of coagulation factors.
