The normal value range of prothrombin time is 9~13s.
Prothrombin time is an index that reflects whether the exogenous coagulation pathway is normal or not, and the normal value range is 9~13 s. Prolongation of prothrombin time suggests that the coagulation function is poor, which may lead to skin petechiae and ecchymosis, arthralgias, intracranial hemorrhage and other hemorrhagic disorders, and generally is greater than 16 s. It is of clinical significance.
Shortened prothrombin time suggests increased blood viscosity, which may lead to cerebral infarction, intravascular thrombosis and other thrombotic diseases.
Abnormal prothrombin time may be related to liver function damage, severe infection, malignant tumors and other diseases, it is recommended that patients with abnormal prothrombin time need to go to the Department of Hematology in a timely manner to improve the relevant examinations to clarify the specific causes of the disease, and then carry out the treatment for the specific causes of the disease, so that the prothrombin time can be restored to within the normal range as soon as possible.
